My most valuable coins

In this swap you'll have to write your partners about your most valuable coins. By 'valuable' I don't mean only money. It might be a coin you have a sentiment for or maybe it was hard to get it or maybe you received it from a precious friend or it has a funny history (for example you exchanged it for a cow but it returned to you after 10 years ;). It's up to you how many coins you would talk about. It would be nice if you added photos.

I'm making it electronic to see how many of you is active. You'll have as many partners as participants will join so that we would get to know each other. You can also add some information about yourself, if you want.
