Overview
Since 1478, the hallmark has included a distinctive date letter indicating
the year of hallmarking. Consequently, there has been a temptation
for centuries to make an article appear older than it is by using
counterfeit punches, or by transferring a genuine hallmark from an
antique article into a more modern article. This is an offence under
the Hallmarking Act 1973. It is also an offence under the Act to alter
a hallmarked article without the written permission of any Assay Office.
Articles which have been altered legitimately bear an 'additions'
mark, indicating the year of alteration.

Antique Plate Committee
The Antique Plate Committee (APC) examines suspect silver articles
and advises Assay Office London on the genuineness of the hallmark
and whether there has been an illegal alteration or addition. Each
article is given a case number.
Makeup of the Committee
The APC, organized by Assay Office London, meets approximately
quarterly. It comprises 10 members who bring expertise in antique
silver from a variety of perspectives; dealers, academics and collectors
are all represented. Members of the APC serve for a fixed term. The
APC is supported by an extended panel of volunteers who help report
and inspect potential problems in the trade.
Procedure
An article may be submitted to the APC free of charge. A receipt and
a Notice of Procedure
are issued. The latter describes in detail the treatment of unauthorised
marks. The APC considers the article through a combination of objective
scientific testing and connoisseurship. Discrete samples may be taken
in order to establish the approximate age of the article by spectrographic
analysis. Other non-destructive scientific methods, and comparison
with genuine hallmarks of the period may be used in order to assist
the Committee in reaching its decision. The Committee's decision is
final.
Treatment of Unauthorised Marks
Section 7 of the Hallmarking Act 1973 specifies how an Assay Office
must deal with unauthorised marks and unauthorised alterations and
additions. Depending upon the age of the article, the unauthorised
marks will either be cancelled, or obliterated. The owner then has
the option of submitting it for hallmarking as a new article, and
being charged accordingly, or having it marked with LAO and the case
number.
Informing the Owner
The owner, or person appearing to have control of the article, is
informed by a letter from the Assay Office of the decision of Committee.
This may be a simple statement that the article complies with the
Hallmarking Act 1973. For articles which do not comply with the Act,
the treatment of the marks, and the subsequent options are specified.

The possibility of overlooking a fake or forged piece of silver continues to daunt experts, curators and collectors. Often the skill to identify counterfeit or transposed hallmarks seems beyond reach; what physical characteristics are indications of an altered piece of antique plate? What clues are there that an article is an illegal cast duplicate of an authentic original? How do the experts come to their decision on an object’s authenticity and legality? What actions are taken when a piece of silver is identified as a fake or illegally altered? The Assay Office London’s Fakes and Forgeries Seminar aims to answer such questions by combining educational lectures with first-hand contact with examples of authentic and counterfeit silver objects.  |

The seminar comprises a morning session which explores the definition of a fake, current legislation, the operation of the antique plate committee and culminates with a perspective on detecting fakes from a renowned expert in the field of antique silver. The afternoon sessions provide an exclusive opportunity for participants to handle spurious articles from the Assay Office’s Black Museum, the largest known collection of fake silver worldwide. Acclaimed silver specialists lead table discussions and train participants’ connoisseurship in the identification of fakes and forgeries. Each table provides unique examples of fakes, including such common examples of spoons converted into forks, transposed marks and articles made from base metal. In addition, examples that continue to perplex experts are discussed, thereby ensuring that all levels of expertise benefit from the handling sessions.
