Sorry - accidentally made the suggestion in the non-tradeable version. Making it in the right place now.

This one's iffy - I'm aware of at least two based on what backpack.tf tells us. (Don't have premium though, sorry if I miss any others with movement)

The trade was 1:1, so there's two values that could be used: the sell order value, and the value of a Sunbeams A Hat to Kill For.

https://backpack.tf/profiles/76561198049100395#!/compare/1757203200/1757289600 (Way less useful to look at)

The price of the Sunbeams is a year old, but we have a recent suggestion.

https://backpack.tf/suggestion/68bb958a6c2790d7cb09c266

The Overcharged sell order's price was listed at 120 keys, but the current suggestion ongoing for Sunbeams is ranged from 122 - 135. However, one would argue that the exchange, by design, is overpayment compared to the sell listing, so it should be capped at 120 keys regardless.

As usual, if this suggestion is insufficient, it can be used as a reference for later.

Small update - there are at least 3 out there.

One was without movement: https://backpack.tf/item/15969696405

One was bought by a collector from a trade bot without keys changing hands, so hard to price without them proving it. : https://backpack.tf/item/15970922017

Thanks for finding these. We'll probably need to close this suggestion and open a new one with the accurate price range.

Closing and re-making.
