It looks like 29 keys + 1 ref, but the buy order was 65 keys + 1 refined, so I assume it was that

The taunt was also listed at 79 keys for some days before it sold to the buy order

Some buyers at 70+

One seller at 100 keys, young at 100 but has owned for about 3 weeks

111 is the same value ($200) at 100 key sales now, so I feel like it should be included

Going with 79-111
