auctions at GB. See what ones that look like the ones you looked at are selling for. It is sort of a "I have a chevy what is it worth" question. I see what I assume are run of the mill 101's in local auctions here ( nice guns) for $500-1000 or so. I have a buddy who is into high end O/U/ SBS type shotguns, and he will pay really big dollars ( like MG dollars) for some guns. It really depends on what the 101 is, and features and gauge, and chokes, all make it unique and unusual or not. so the answer to your question is a solid maybe. If you buy one for $400, you will do ok. If you spend $1000, you may make money, you may lose money.
