Nice to see a good old bidding war. But one should know not to go head to head against greenplastic without bringing out the big guns
My guess is that the original owner of these coins had every intention of purchasing them as funded, leading smoothie to ship him the set without the mark of "buyer funded". But instead the circumstances changed which forced the buyer to not load the coins. Perhaps an unexpected expense or emergency came up requiring the buyer to justifiably use those BTC on other things.
If this occurred between the time smoothie shipped the coins out and before the buyer received them and instructed smoothie to complete the funding, it would explain why these are not an "error" so to speak, but an unfilled commitment by a buyer.
