I purchased a large box of old tins at a local estate auction that included 18 of the Colgan 's Chips round tins. Of the 18 tins I have noticed there are quite a few different tins. There is Mint and Violet of course and then some have a Food and Drug act, some do not, some have copyrights some don't, some have Louisville some have N.Y.. My Question is are any of these tins more scarce than the others? I have collected the chips for 10 years but I don't know anything about the tins and was hoping a board member could help out with rarity of the tins if any. I have ordered issue #19 of Old Cardboard which has a article on the Chips. Thanks Daryl
