some of the holders used are pretty inexpensive, cardboard 2X2s, usually anywhere from 3-6 cents each, some can go for a dollar or so, airtites ferinstance. Before you holder the coins you should have an idea wether it is worth doing so, your local library should have the books you need, wether it is for foreign or US coins, If it were me I would not holder any coin worth under a dollar.
OK, I need to get these coins organized, any favorite web resources for "stuff" to keep these coins in? Forgive my ignorance...
