What makes this so unusual is that I am in Canada, 400 miles North West of Winninpeg, in the town of THE PAS. This town is situated on the Saskatchewan River and was origonally settled as a major fur trading location. It has been historically a hunting and fishing destination for American sportsmen, and there was a US Air Force radar installation 15 miles north of the town for decades. I can only assume that this buckle was in the possession of one of the soldiers. As well, the Hudson Bay Railway line was built in the 20's, and I understand that many of the construction crews were from the US.
There is a park on both sides of the main hyway that runs through the town, and has remained undeveloped and used as a meeting place and green space since the town was built. This park has yielded a large number of coins from the 1880's up, and jewelery over the years. The best coin to date is the Canadian 1921 5 cent piece my brother found in the park. This coin was sold three years ago for $ 3,000 cdn, and is now worth twice that amount.
Thank you all for helping with the identification of the snake buckle and i wish you all good hunting.
