I highly recommend Lost Dutchman Coins in Lawrence. They have been very patient with me when I come in and ask a ton of questions I can't find answers to online.
They will sell you junk silver under melt for INGO members and they have Silver Eagles and prevately minted bars/rounds most of the time.
+100
They run a great little shop and the staff are all very helpful and awesome to work with.
Plus they are an INGO site supporter.
