the Hat with No Name only has 2 other sales

First one is a Quicksell.Store dump for ~33 keys (same person who sold the Topper), but they also dumped multiple cosmetics with it:

https://backpack.tf/profiles/76561198850121720#!/compare/1706227200/1706313600

The buy order was ~25 keys so that's most likely what it was valued at https://next.backpack.tf/classifieds/snapshots/Aces%20High%20Hat%20With%20No%20Name/65b394407f12e82e5f0a0370

Second sale is untraceable:

https://backpack.tf/profiles/76561198119693227#!/compare/1706832000/1707004800

Since the Topper seller dumped the Hat with no name to Quicksell.Store, 25 is probably the most representative value to use as a mini
