You can get the yearly proof sets from the mint and leave them in the GPO holders. You didn't say how you are going about collecting these proofs, for example, placing them in a coin album or board. In that case, you can buy the proofs individually from sellers here and on e-Bay if you are leery of cracking open the GPO cases. If you plan on handling the coins, having a pair of Colton gloves is handy so the surfaces aren't marred from the oils from your hand. Good luck and welcome.
