That's a nice one.....a bit grubby, but looks like it would clean up real well...."A" Code is not an everyday occurrence, so it's "worth" maybe more than your average Blackie 3-wheeler 22"....
The "worth" & "value" questions are weird, it does kind of depend on area, what you have to fork out, if they're asking something "reasonable", how much you want the item, etc.
