The Peters box is too new to have much collector value being a post 62 with the child warning label. Usually only worth 20 to 25 bucks. the older military loads are more desirable but from experience they can be hard to find a buyer. The 45 in clips looks nice and would probably sell in the 50+ range. The 20 rd 45 box is a common style and rarely sells for much more than 30 to 35 (I carried a couple of these on the show circuit for 2 years before I found a buyer). The military buckshot also seems to show up a lot, individual shells sell for 5 to 10 each, a full box should bring something around 75+. No idea on the military 38's, have never had any those before. Maybe 50 each?
I have seen people asking much more for some of these but they usually don't get it. At least not on the regular gunshow circuit, perhaps at a specialty cartridge show or on the internet. From my own experience there just aren't all that many people collecting these and it's hard to find a buyer.
