Hello,
I recently began collection random coins from antique stores, and some time ago I bought a Third Reich 1 Reichsmark, minted 1936 at Karlsruhe (indicated with a G) for £2 GBP.
When I started setting up my collection on this account I noticed the version I had was indicated as rare. Only 620,000 of these were minted, so should I take it that this coin has much more value than £2 or should I be suspicious? Photos below.
