Stamp inspection

from Wikipedia, the free encyclopedia

The stamp inspection is used by the philatelist to assess the authenticity and degree of preservation of his or her collective goods ( postage stamp , postal stationery , whole piece , letter piece and so on) by independent experts. The more valuable a collector's item is, the greater the risk that it will be forged or falsified, or that repairs that reduce its value will be concealed. The results of the examination can be noted (signed) on the collector's item or recorded in a certificate.

history

One of the first German auditors was Alfred Moschkau (around 1871), who at that time tested hundreds of stamps a year free of charge using his worldwide reference collection. It was not until 1877 that Waldemar Herrmann followed in Berlin, who now also took fees for his exams. In 1905 there were around 150, mostly specialized, examination centers in Germany, which were often affiliated with associations or dealers. However, general examiners without specialization continued to exist well into the 20th century.

tester

Postage stamp inspectors are experts who specialize in certain subject areas and / or inspection areas (temporally and / or regionally). There is no state-recognized training. The reputation of a stamp inspector is therefore primarily based on his reputation, which he has acquired through his professional competence, which he has mostly acquired over decades. Membership in an auditor association requires the completion of internal examinations with proof of competence (technical test methods) and proof of a reference collection. The member thus submits to the test rules and the code of honor of the respective association. The effectiveness of this self-control is repeatedly questioned and the proximity of inspectors to stamp dealers and auctioneers is often criticized.

Stamp inspectors check philatelic collectibles for authenticity and quality , mostly for the degree of preservation . The test pieces are increasingly being signed less and less (stamped on the back with the tester's name), instead a "brief report" with a photograph of the test piece is issued, and if the value is higher, a "finding" or a "certificate" is issued. Findings and certificates are provided with security features on paper or by means of a hologram . However, counterfeit stamps are marked as such by the stamp inspector (at least in the past, but not necessarily for all associations). You will get the stamp "Wrong" on the back. Partial forgeries are also identified as such. The stamps in these cases read, for example, “stamp wrong” or “rubber wrong”.

The auditors' associations define the most uniform standards possible for their members with regard to the scope of testing and testing procedures.

“[...] The findings of an examiner on a philatelic test item can usually not be made with absolute certainty, but only with a high degree of probability. There is no generally applicable procedure for checking philatelic objects. If necessary, the auditor has to apply various procedures in order to arrive at an accurate audit opinion.
The examination is carried out on the basis of the knowledge available at the time of the examination and the existing comparison collection. [...].
Furthermore, data collections (e.g. registers of the better and forgery-prone items in the test area, copies of the certificates drawn up by the testers, auction catalogs, stamp images, literature) are necessary for testing.
Confirmed research results of philatelic authors and working groups as well as postal and contemporary background to the test area must be taken into account. "

The examination can take different lengths of time depending on the workload and workload of the individual examiner. The principle of economic efficiency also applies: test methods that are usually not available to the tester or that are associated with costs that go far beyond the usual level (e.g. isotope method, C-14 age determination, X-ray fluorescence) are excluded .

The costs of a test are based on the information in the test regulations of the respective examiner or testing association, as a rule they amount to between 2 and 4 percent of the catalog value of a test piece, whereby in the test regulations often minimum fees per test shipment and test object as well as fees for the signature or respectively Type of certificate (brief report, report, certificate) are shown.

The quality, duration and costs of processing are repeatedly criticized by customers and internally by auditors.

Approval mark positions

At the owner's request, the inspector can, in accordance with (at least in Germany) uniform regulations, place a test mark on the back. The position makes statements about the test object. Auditor signatures usually consist of the auditor's name and (for several years) the abbreviation of the auditing association. The signature is attached to the back of the stamp with a stamp . It is relatively small compared to the postage stamp. There are different positions for the signatures. Unused stamps are otherwise signed as a stamped , stamps without printed as stamps with such a well serrated pieces other than cut . The signum also provides information about the state of preservation of the stamp through the distance from an imaginary baseline.

Fake certification marks

Since collectors prefer verified stamps for understandable reasons, counterfeiters have also recognized the possibility of forging the verification stamps from renowned inspectors. Often, wrong test stamps reveal themselves by the fact that the letters of the name of the tester are unevenly large, not upright or not in an exactly straight line. In case of doubt, the marks would have to be presented again to an examiner for control.

Example of a forged BPP test stamp on a real stamp. Because of a forged cancellation in this case, the stamp would have increased in value quite a bit.

Examiner associations and test centers

German-speaking area

There are several testing associations in German-speaking countries.

country Association founding Number of examiners
D. Association of Philatelic Auditors e. V. (BPP) 1958 103
D. Association of Philatelic Auditors V. (VPPEV) 2010 19th
A. Association of Austrian Postage Stamp Checkers (VÖB) 1921 24
A. Association of Philatelic Experts (VPEX) 2012 12
CH Swiss Stamp Examiner Association (SBPV) 1987 11

Association of Philatelic Auditors

The Association of Philatelic Auditors e. V. was founded in Munich in 1958 and in 2013 comprises 106 active examiners as well as 12 senior citizens and 12 publicly appointed and sworn experts. In 2013 around 80,000 medical certificates and brief reports were issued. Christian Geigle has been president of the association since 2011.

The quality, duration and costs of processing are repeatedly criticized by customers, but also internally by auditors.

Association of Philatelic Auditors

The Association of Philatelic Auditors e. V. was founded in Münster in 2010, most of the VPP examiners were previously members of the Association of Philatelic Examiners , from which they have left. In 2017 there are 16 reviewing members. The 2017 board consists of: Lothar Herbst (1st chairman), Reinhard Hofrichter (2nd chairman), Robert Brunel (treasurer) and Axel Dörrenbach (branch manager, public relations). Former chairmen were: Udo Eberhard Klein (2010–2013), Carsten Burkhardt (2013–2014) and Lothar Herbst.

In several trademark protection lawsuits initiated by the Bund Philatelistischer Prüfer (BPP), the association was forbidden to continue using the previously used abbreviation “VPP” in the test stamp and on certificates: The court saw a risk of confusion with the abbreviation “BPP”.

Shortly after it was founded, criticism of the integrity of the association and individual members came from the stamp dealers' association APHV, the stamp auctioneers association BDB and the collectors association BDPh .

"[...] Against this background, the BDPh researched the services of the Association of Philatelic Examiners, reviewed their inspection regulations and held intensive discussions with representatives of the Federal Association of German Stamp Auctioneers (BDB) and the Federal Association of the German Stamp Trade (APHV). As a result, it became clear that, in our opinion, the Association of Philatelic Auditors and its members are not achieving these standards to the extent desired. [...] "

- Association of German Philatelists : Declaration by the BDPh

It was also criticized that the test regulations (compared to the BPP) are much less precise and that there is more room for interpretation.

United Kingdom

In the United Kingdom, stamp testing is carried out by a committee of experts from the Royal Philatelic Society London . The then Philatelic Society London founded an Expert Committee in 1894 after several forger scandals . Around 217,000 certificates were issued up to 2013, with around 2,500 to 3,000 more each year.

United States

As in the United Kingdom, in the United States, testing is mostly done by committees of experts, including the Philatelic Foundation and the American Philatelic Society (American Philatelic Expertizing Service - APEX). The Philatelic Foundation has issued several hundred thousand test certificates since 1945, and the APEX of the American Philatelic Society states a total of over 210,000 tests in 2017, which corresponds to an average of 615 tests per month.

International Association of Philatelic Experts (AIEP)

The AIEP is an international association of independent auditors, some of which are also members of national auditor associations. It currently has 104 examiners. The aim of the association is to bring together, cooperate and exchange views among the leading stamp validators worldwide. The AIEP works with other international and national organizations in the fight against stamp forgery.

The association was founded at the "1st Philatelic Experts' Congress" in 1954 in Merano . Ferdinand Wallner , Ladislaus Varga, Hans Hunziker, Enzo Diena, Emil Rellstab, Wolfgang Hellrigl, Carl Aage Møller and Klaus M. Schöpfer acted as presidents . The current board (2017) consists of Thomas Mathà (President), James Van der Linden (Vice-President), Igor Rodin (Director) and Paul Wijnants (Secretary).

Awards

Since 1996, the Köhler auction house has awarded the so-called Köhler Prize for “extraordinary services to testing”. The founder of the auction house Heinrich Köhler was himself an examiner.

In one case, collectors as well as dealers and auctioneers voiced a large number of negative voices regarding the, carefully formulated, very imaginatively designed inspection fee calculation. […] Furthermore, one of the eight members listed has issued an affidavit (August 26, 2008), another is in the process of insolvency (opening of insolvency on May 4, 2007), and irregularities can also be documented in a third "examiner" (see just now judgment given, District Court of Konstanz, Az. 40 261/2010). Anyone who has given an affidavit does not have the financial means to be liable in the event of a false examination, although he is obliged to legal liability.
