Really, thats cool. I have a partial set of president stamps that were given out when at least $2 of gas was purchased. I'll have to stay on the look-out for others, thanx...
IIRC they were from the 70s, given out by Texaco, and were generally given to children to occupy them on long trips. I have a cardboard display card for them, and a few of the coins. The card is similar in concept to a Whitman folder, but it doesn't fold closed, and it doesn't fully cover the back of the token so that you can read the info.
If you have a full set, they can be sold on ebay. If you are lucky, you could put this up and 2 idividualy need this one for the full set and bid it through the roof.......
