It's hard to pick one favorite ... so many to choose from in this thread ... but I think i agree with the people above ... that 1820 large cent is my favorite thus far! Anyone know what would that would grade?
Here's one of my new favorite coppers. My four year old son pulled this out of the local coin collecting club's kids free grab bag at a coin show this week-end.
What a wonderful 1820 (N-13, IIRC) from the Randall Hoard. Just a subeprb example (that I like even more than my own!).
I've seen a lot of beautiful coins posted as favorites on this thread, but this ugly duckling is mine. Not because of value or beauty, but because it was one of my dad's coins that he left to me when he passed away almost 20 years ago now. This means more to me than anything I have in my collection today. I'll always miss him, but I always have this to remind me.
In that case, that coin is more valuable than one in mint state. I don't have any coins that have a personal meaning. Don't let it go.
