What is the value of this 1969 Schwinn Stingray 5 Speed bike?
Maybe it made the Blue Book if you wanted to check the price however 1969 was 50 years ago, so that might be quite awhile!
On ebay it's selling between$1500 to $4000.
Like any other so-called collectible, you can find out how much a similar item sold for on ebay by looking at completed auctions. Don't rely on the asking prices. Sellers are often delusional about the value of their items. PS Ebay shows many Stingrays in good condition selling for between one and two thousand bucks. It's hard for me to believe, but the evidence is there. Take lots of good pictures and describe it well and you may cash in like that too.
If it's in great condition I guess you might get £25 or so for it for retro novelty value.
