You don't have to have a large inventory to lose something, even something significant; I lost the only B18 I had and did not find it for so long that I actually deleted it from my insurance list (I figured I must have traded it off in some deal I could not recall). It turned up under a stack of album sheets of modern cards that I was prepping to give to my nephew.
If the guy has good feedback as a seller, I'd take the proffered excuse at face value.
