Not sure if your mini is correct. Several groups of keys also enter his bp that day which may be from items that were also involved that were sold to bots the very same day. may be worth verifying that

Also its probably worth at least listing the 2nd sale, and label the mini as a mini; as it looks like your mini is a 2nd sale :P
