1890, the first zipper was invented but there wasn't a price because the guy who invented it was a simple man at the fair. The only price for I zipper I found was in 1930 which was riced at $1.39. Hope this helped. :)
The zipper was invented by Whitcomb Judson in 1890, but there was no set price for it at that time due to its lack of commercial success. It wasn't until the 1920s and 1930s that zippers became popular and were priced, with zippers costing around $1.39 in 1930. Thus, zippers were new and not widely used or priced in 1890.
