Depends on what variation you may have. The ones with the "R" are about 35.00 to 50.00 depending how bad someone may need it. Now if you have the buckle without the "R" I have seen them upwords to 125.00. These prices must include the original box.
Figures...one is sealed still in it's box. The other is 1/2 sealed so I could check. It's an ® one. Guess i didn't do bad on them after all. Were they not boxed/sealed I'd have passed but as they are, they make for good display stuff.
