    Mary I Groat

    Hello.I have just purchased a Mary I Groat from a experienced coin dealer but it doesnt ring like a coin when I drop it on my desk, and has a low Specific gravity. I noted in a forum topic from 2012 mention of a Mary Groat database of fake coins. Could someone please compare my coin or advise me of how to find this database. Any advice would be appreciated. Thank you.

    Charles I Sixpence Sp 2800.. 3a?

    Thank you for your advice
  3. Hello, I am new to this site and to collecting Hammered coins. I have just purchased my first coin that I think is a Charles I sixpence Sp 2800...3a. It is crown mintmark [1635-6] which is what the dealer sold it as. My question is it only weighs 2.69g which appears to be quite light for a sixpence. Would a Charles I expert mind looking at my coin and comment on it and the weight please. What do I actually look for in a hammered coin. They appear differ vastly from each other. The diameter is 24.4-25.1mm and it doesn't appear to be clipped. Thank you in advance for any advice. Michael
