I just counted (from the picture) and it looks like 56 or so. I probably could have fit a few more in. I only have one or 2 $5 Indians at the moment.
If you really need a bag of gold you have to bury it and create a map. Ask @Jason.A for details as to how to bury gold.
Bullion is bullion so the condition of the coin or bar really doesnt matter However keeping it in nice condition is important to me, just like things Bright and shiny I use tubes for all my 1 OZ Gold Coins in (32MM) w/ Lock-tites As well as my 1/10 OZ Gold, APE,S in (16.5MM) also w/ Lock- tites
