Thank you for submitting your item for appraisal. These appear to be old trading stamps. They were part of a loyalty program of a department store or similar. The savings plan was described as this: With each 10-cent purchase you receive one eagle stamp, which are then pasted in a booklet. For each filled booklet you receive 2 USD in cash or 2.50 in Trade. Trading stamps in general are quite common and the number of collectors is small. The current value on the collecor´s market is rather low unfortunately. The estimate is based on similar sets actually sold at auction.
