S - Old American Insurance Company Coin Stamps
These three Coin Stamps came from mid-twentieth century mail order solicitations of the Old American Insurance Company which was founded in 1939. The solicitation provided an application card with a space for inserting a coin to pay for the first thirty days of coverage while the application was being processed. A denominated Coin Stamp was provided to secure the proper coin in place so that it would not move around in the envelope and/or get lost in the mail. The Coin Stamp was typically stuck to the solicitation letter, which accounts for the fact that many of these stamps are found with gum disturbances particularly at one corner or along an edge.
