@coop - yes it will be difficult but what I love is that my 14yr old daughter found this. I started sending them coins from Belize when I lived there 3yrs ago. My daughter and my 11yr old son keep every piece of change they find and use my microscope more than I do lol. They have been collected for about a year now. Her favorites are over-polished / strike through (she tries to draw what is missing from the coins). I'll ask her if I can post a pic or two, it's really neat. My son just likes anything that looks strange lol (especially machine double). I just love the fact that I'm 40 and can sit with them without music blasting or them fidgeting around haha.
@macmercury - thank you for the info. I will see if I can look up that info up online.
