There was a recent Pawn Stars episode dealing with reproduction banks. It is very hard to identify them. As I understand it, you need to look at the screws on the bottom first and idendify if they are mass-manufactured (modern) or if they were individually slotted. (slots are a little bit off because they were done one at a time). Second look at the paint loss. It should not look too new and you should see "rubs" on the high points of the casting consistant with use. Third you need to research the particular model of bank and learn what the castings look like on known, identified originals. The bottom should be your best way to identify it, look for makers names, quirks in the casting etc. Another way to ID reproductions is that 19th century craftsmen took more pride in their work and parts fit solid, seams filed down and hidden etc. Banks can tough to ID! The reproductions look so real!
