In general, items made for the collectors market do not hold much value. Companies mass produce things called collectibles sell to people who like to collect things and produce a high volume of the items. In the 1980s a collectible craze sent people buying all sorts of things.
American Collectors Guild produced brass souvenir spoons that featured states of the U.S.A. as well as spoons depicting the heads of American presidents. If you wish to learn about the value of these types of items, look around online to see what they are being sold for, check sold prices not asking prices. These spoons turn up at thrift shops. I have seen individual ACG spoons being offered for as little as one dollar a piece.
