If you read my posts you probably know that my coin collecting sweet spot is unusual, obscure places that issued coins, especially if there's an interesting historical story, and Danzig certainly qualifies. The Free State of Danzig existed only a short time between the world wars, having been carved out of Germany after WWI and incorporated into Poland as Gdansk after WWII. Danzig did not issue a lot of coins, but there were a few different years when coins were produced. I don't have all of them, and the higher denominations get quite pricey, but here's what I have. Feel free to add yours as well.

Dajo, do you know anything about these C/M's I have seen them years ago on other non-Danzig Prussian thaler coins and they were thought to be fantasy issues by who ever wrote an article in Money Trend(1970's ?).
Dear Fred, The history of these pieces is difficult to reconstruct. In the years of the great inflation several cities adopted countermarks on existing coins to guarantee sufficient 'value' to make payments, or made their own coins. However, shortly hereafter also fantasy coins were struck, most notable by Bruno Röttinger, a German numismatist. These are notably coins with a new design, of coins copied from a design previously issues by the autorities. Walter Funk, in his Die deutschen Notmünzen, distinguishes several types of fake coins: 1. Restrike with the original stamp on original coin plates, which do not differ from the original, 2. Restrike with the original stamp on not original coins plates, which differ from the original in diameter and/or thickness, 3. Issues with the wrong stamp coupling, that is, mostly the obverse stamp is the original, which was coupled with another reverse stamp 4. Issues that differ from the original in form and material, 5. Emergency coins without the official perforation, 6. Emergency coins in which the nickel plating is missing or has been specially applied, 7. Emergency coins for which a new stamp was specially cut. The specific countermark as seen in my Danzig 5 Gulden does not fall in one of these categories. So it may be official, or it may be another 'forgery'. At least it must originate in the years of the great inflation, so in some sense it is still a historic coin ;-)
