There are no known serial number records available for Lincoln Canoe so no one here can offer much more information. They have changed owners several times and I suspect that much has been lost in each transition. Dan's link may be your best hope. If it was made after 1972 then it should have a hull identification number on the starboard stern. See https://www.usps.org/national/safety/HIN/HIN.pdf for more about how to interpret this number which contains a two digit date code at the end. Fiberglass canoes commonly sell for a few hundred dollars. Good luck with the sale,
