I have a couple of like new men's chains. One is a Cuban Curb design (6mm links, 38.8 grams, 18"). The other is a Figaro design and has a matching bracelet (6.8mm links, 37.2 grams, 20"/ 6.8mm, 22 gram, 8.5" ). They are fairly heavy and come with papers from the store they were purchased from. They are very nice (appraised value on the three is nearly $4000) and in mint condition. I am open to trades on them for just about anything of value (but prefers guns...ha.) I do not expect to get anywhere near the appraised value, so make me some good offers.
