i would use that bank to exchange it for something you can hold. some thing some local party will trade you cash notes for when you need those, without questioning where you got that stuff from (without having to prove it belongs to you).
pre 1965 dimes, quarters, halves and dollars, and bullion in forms the local parties are willing to exchange a premium for such as eagles and maple leafs (things they can A, easily inventory, B, easily redistribute).
