I recently starting collecting silver eagle coins and silver bullion coins due to the increase in demand and the fact that I think it is a good time to be buying silver and gold. My favorite is pictured here and it is the American Eagle Silver Dollar. These silver American eagles are good assets to have and I recently became associated with a Silver Eagle distributors called NumisNetworks. Numisnetworks deals in silver bullion coins and they deal a lot in the American Eagle Silver Dollar. If this sort of thing interests you, you can check out more at this Silver Eagle Coins site.
Numisnetworks is a membership that autoships you a new coin each month. I think it is one of the coolest ideas I have ever seen. You collect assets each month that typically and historically have kept or increased their value.
