We all have seen antique silver crown coins with deep scratches in groups, paralels or/and crossed. I have understood that they were made to remove the silver excedent and adjust the weight of the coin when it was minted, then are called "adjustement marks".

Most I have seen are in coins of XVIII century, but I have seen these marks on coins of middle XIX too, Bolivian and the Italian States coins, I am coming in mind at this moment.

Is it possible or might be a red flag? Does anyone know until when the adjustement marks were used?

The latest marks I have seen on French coins are Louis XVIII pre 1820, and extremely uncommon by that time. I could not find a single example on cgb.fr, in past or current sales. Here's an 1817K 2 Franc:



To mee it looks like the adjustment scratches were made on the planchet before the coin was struck, taking away metal so that the dies could not strike through them completely. They usually show on the deepest relief, and unfortunately are usually right on top of the portraits.

They also exist on early 19th century German States coins. You can find them quite often for instance on Prussian 4 Groschen and 1/3 Thaler coins that were minted between roughly between 1800 and 1810.

By the way there seem to be many 19th century coins that show adjustment marks. If you check ma-shops.com and type the term 'justiert' (German for 'adjusted' in the search field and filter for coins between 1800 and 1900) there are about 200 pieces from all over the world that are listed at the moment.

thq: I agre with you, until around 1820's are the latest adjustment marks (A.M.) I have seen on French coins.

Potsdam: good search, thanks!... I have found this Prussian 2 Thalers 1867 C, it is an example what I mean.....Had not been standarized in Prussia in 1867 the weight of the planchets yet? really I do not know, but if the answer were YES, then a coin with A.M. would be a numismatic forgery. Do you understand what I mean?

Typically edge adjustment marks go across the rim.

I don't see that on the Prussian coin, and am suspicious.

From the coins I have seen with adjustment marks I would replace "typically" with "often" in the quoted statement.

Exactly. I haven't seen any adjustment marks like on that Prussian Doppelthaler. However, the dealer who offers it has a pretty good reputation, which is why I probably wouldnt be bothered buying something from him.
