I Went to a Estate auction and purchesed 2 pairs of handcuffs and would appreciate if you could help me since your a collector and I know nothing!One Pair is Peerless #507884 (1971) yr. 2nd is Hiatt # 575717 What is the value of the peerless? And the yr and value of the Hiatt? This is a way kool site,I never imangined! Maybe Ill start collecting Too! Thanks so much,C Petersen Tigard,Or

While neither set is particularly rare, the values would be largely dependant on their condition. I might be able to give you an approximate date on the Hiatt if I saw a picture.
Please post one, if possible.
