From our FAQ -
The true value of vintage bicycles and components can be difficult to determine. Unlike other "collectibles", there isn't a BMX pricing guide. A fair price is one that will make you happy when you buy or sell something. If you are happy with a price, then that price determines the value of your item.
Bottom line: It's worth whatever you can buy it for or get someone to pay for it. VintageBMX.com is a resource for vintage BMXers, a pricing guide it is not.
If you're not sure what that price should be, consider an auction. If you don't want to sell it because it's really worth more than money to you, we understand completely. We're more interested in the attachment to BMX, and the value of that is beyond money.
