I've been watching Edward VII Maundy sets on ebay for a few months now. I finally found one that I like with good pictures but the bidding seems somewhat suspicious to me. The seller is also selling a George V Maundy set and the same three bidders have made bids of the same amount on each of these listings. The seller doesn't have any feedback in the last 12 months but has been on eBay for over 10 years. From watching other auctions sell and similar BIN listings I have an idea of what I can expect to pay and what I'm willing to pay. Is this bidding a a major red flag? Should I just forget about it and keep looking? Thanks for any input.
