I'm not a collector, just a shooter that loves SxS's, with hammers on them even more so. None of mine are very expensive $200-500. But I shoot them well. I reload for all my hunting and have enough Bismuth for a few years. I wouldn't have a problem opening the chokes on a new of my old Husqvarna and run a mild load of steel through it, I just have to wait for them to get a little closer. My go-to load for waterfowl 7/8 oz of 6's out of my 12ga.
We can always melt down pennies and make shot. People don't even bend over to pick them up any longer.
