@panzerman may I ask, do you collect stamps? At the economy shop where I volunteer we received a lot of war and pre-war stamps, not only from Germany but also from the Netherlands and other countries. If you are interested please let me know by PM.
It depends on what you consider valuable: the 1984 pattern Piefort commemorative coin from Uruguay, issued to mark the BID meeting.

I'm not sure from a value stand point what mine are worth but these are from my collection of world aluminum coins
