Value of S Shaped Dollar Cuff??

Would like help in determing value of a pair of S shaped commonly refered to as Dollar cuffs. Good condition with no maker mark and repairable lock? with no key? Anybody have an idea as to worth?? Thanks

It's hard to determine the value of a "Dollar-Handcuff", because I cannot remember this model being sold (e.g. at eBay) in the last 2 years. But considering that a "Dollar" is in any case as rare (I would say even rarer) as a Stotz, a "Dollar" in good working condition and with key should bring at least US$ 1,500.00. BTW: there are two versions of this restraint: one with a barrel and the other with a flat key. AFAIK the one with the flat key is the rarer version and therefore of still higher value.
