Thank you all. I learned from the en.numista.com website there are 4 different 1927's: 1.
no mint mark, 2. proof, 3. Heaton (H) mint mark, 4. Leningrad (L) mint mark. My coin has the H mint mark I believe.
I find that very interesting as I have never seen or heard of a coin that would have been minted at Heaton and Leningrad.
I plan on selling the coin, and would like to get maximum value, but unfortunately there are some shipping restrictions which currently limit my potential audience quite a bit.
I wonder what mintage figures are? Time to dig in for some research.
Thank you all for the awesome effort. It is much appreciated.
