I'm fairly certain remchester is not an avid shotshell collector because I am looking at a recent auction sales list for brass shotshells and to my budget some of them are pretty pricey. But I will agree that shells dug from the ground are probably nothing of collector value, unless it is a 4 1/4" 3ga Winchester No. 3. One of these recently sold for $800 so a recovered fired case might be worth a few $s. There are a number of brass shotshells that have considerable value fired, but in otherwise good shape.
