Where to start, I am currently sorting through a coin collection that I bought off my sister as she no longer wants them.
I am on the Spanish coins now and have tripled checked what I have discovered. However, I might need a little help with trying to get a better understanding as to why such a coin that is only minted as proof has come into my hands looking quite circulated.
I do have the usual theory of someone has begun using this coin as normal and it went from there. I don't know but, it would now be not as valuable correct?
