I've been watching Storage Wars on TV where people bid on unclaimed storage units, so I thought I'd give it a try. I bought one that had some old reloading equipment, a few old gun cases, a rusty model 12 and three of these glass balls. I was juggling them and dropped two, but I still have one left. I know in the old days trap shooters shot them so I thought I'd see if it had any value? It says " Bogardus". Anyone know what it's worth?
