I bought a 2013 ATB proof set on ebay without the Original packaging or COA for $8.25. When I got the set the case was loose and it looked like it had been opened. In fact I was able to take it apart myself without having to break it open(something I cannot do to my other sets). Other than that the coins are in really good shape. The seller is offering refunds within 30 days but I have to pay for shipping. What do you think? Should I return it or should I not worry about whether or not the case is in original condition? Would it hurt the value and would it cause oxidation/toning?
The loose jangle might bother me since i'm somewhat OCD. But I guess the thing that bothers me the most is the possible toning. But Modern none silver proof sets will probably never be worth much in the future. So if I have to buy a replacement in 20+ years it probably wouldn't be a big deal. Heck, I saw a 1985 proofset(the year of my birth) for just $5. Yeah, im probably just being paranoid like usual.
