Hello all,
I'm new here :-)
I seen at eBay that coins sometime describe as 'rare' or even 'X-rare',
My question is, how do I know if a coin is rare ? and when it rare ?
For example, this 5 mark coin
https://en.numista.com/catalogue/pieces5218.html
1939 E describe as rare
but I don't see any reason for it, there was 1,320,000 coins minted this year,
1938 E not describe as rare but in this year there was only 425,000 coins minted . . .
So, I'm a little confused.
Please advise.
Thanks
