Mint set? Proof set? I have no real idea about the differences, sorry-I truly know nothing about coin collecting. I kind of thought maybe Philly coins with a Sacramento penny thrown in. I guess these are in what is called a "flat pack."
Sorry about not being able to add pictures. I do not have a macro lens so any pictures would look horrid up close, or about the size of a postage stamp with little detail.
Lets say these are Philly mint sets, how does one discern a Philly minted nickle, and the no S nickle?
Thanks for your time,
Chuck
