Completely equipment-dependent. They sold 600,000 of them in 1966,
, so basically they are the least-rare collectible car on the planet. Any notchback, (regular hardtop), is a dime-a-dozen car unless it's a K-code, (289/271HP).
Convertibles are almost as super-common as hardtops. Fastbacks are far rarer and the most desirable model. A FB with a V-8 is worth dough. A FB K-code is worth a lot. A notchback is about a $10k car w/ normal V-8 if it's in showroom condition.
Just check eBay completed auctions. There are about a thousand of them on there everyday.
