Many sellers on eBay are just widget movers. They acquire something, and then just throw it out there for whatever price. It is like the Gillette adjustable razors being sold for $600.
I guess if you had a razor that the only way to prove year was by the blade And one year was worth more , you could buy the blade to make it that year... I personally wouldn't but I'm sure there are some unscrupulous individuals out there who would....
