From the documentation (and order form) for this medal:
"Souvenir Medals Struck from Navy's First Ship. Good for lifetime admission to frigate. Thousands of special copper medals, newly-minted from parts of the United States Frigate "Constellation", now berthed in Baltimore, will provide lifetime free admission to the Navy's oldest vessel for the fortunate owners. *** The medals, struck from copper spikes used in the original construction of the ship in Baltimore in 1797, are being used to raise funds nationally for the restoration work required to put the "Constellation" in original condition. The medals are being distributed on the basis of one each dollar donated. (sic) *** Every dollar raised by this means will go towards replacing deteriorated planking, frames, masts, bulwarks and the hundreds of other items needed so that the "Constellation" can remain afloat and take her rightfull place as a national shrine. *** Completed several months before the famous U.S.F. "Constitution", the "Constellation" saw action on numerous occasions during the 18th and early 19th Century. She remained on the Navy's active list until 1955, and during World War II was the flagship of the Atlantic Fleet. A stout link with our heritage, the "Constellation's" preservation is felt to be a national responsibility. *** Donations of a dollar, or multiples of a dollar, which make the restoration possible, should be made to: "Constellation", Baltimore, MD.
