There doesn't seem to be any interest in collecting old primers, that I've seen, but some folks collect the tins, trays and cartons they come in.The primers look fine, but they are probably a collector's item.
The limit of 200 primers per sale is likely why.CCI BR-2 still in stock a year after i posted this. Looks like some CCI 200 LRP also available now 15.99/ 100. Bit pricey compared to some site sponsors.
