I have a set of the medals with the printed booklet.

The Slip cover (white cardboard) and the Folder (blue) both have "The United States Mint" on them.

The documentation in the folder does not have any production figures or cost. However the 1974, 1975 and 1976 Annual Reports of the Director of the Mint did have some information.

The medals are made of antiqued finished pewter and were first available in sets of two at the price of $10, starting April 1 1974.

The album became available to order on April 8th, 1976, also included the 46 page booklet for the price of $5. In addition the album also came with an additional medal "Department of the Treasury", making a total of 11 medals in the set. I find no information in the mint reports regarding the treasury medal.(maybe it was just an added bonus?)

The 1976 Annual Reports states that in total "approximately 2,354,000 medals were sold", There could be as many as 158,000 sets possible (based on the lowest mintage medal), but the total must be less than that since they were initially offered as sets of two for $10. I am sure not everyone completed a set.The period to order the medals and album came to a close on June 25, 1976.

The series of antique-finished pewter America's First Medals were minted by the San Francisco mint as part of the build up to the Bi-Centennial Celebration. An outstandingly researched and written discussion of everything about these medals was issued by John W, Adams and Anne E. Bentley in their Comitia Americana and Related Medals in 2007. As for particulars the mint printed announcement says in part the following:

Somewhere along the way the presentation holder with cardboard slip cover was offered with the detailed descriptive booklet and an eleventh medal - the Department of the Treasury 1789 medal that is at the center for $5.00. For medal collectors on a tight budget this pewter series was/is a great way to share some of the excitement of that period. I got a set with presentation holder for $55. As with most mint products the after-market prices dropped, partially because it was a pewter series and partially it was a medal series versus coins. I saw completes sets selling for $10-$20 25+ years later. In comparison, the Adams & Bentley "the reference" on the series initially sold for $135 in 2007 and you need reasonably deep pockets for any of the actual medals, so it would be a great buy for a teacher or parent to get their little people interested in history!
