Yes, it can be put on a chain. I had it on one of mine. If you really look at the pictures...you can see in all the pics (except the 1st one)...the hollow part where the chain can be put through. . This is a small piece - you can see that next to the quarter, so you just need a chain that fits. I will try to get a pic of it on one of mine before the bid ends.
I got the pictures but it won't allow me to make any edits this late in the auction! : ( If you have an email i can send you the pics of this ON a chain. BUT it is almost 4 AM here now and I probably won't be back on for about 8 hours...
ok ...I uploaded the photos to photobucket if you want to see them. I am new here so I hope this is ok to do! there are 3 new pics here. http://photobucket.com/forlistia
