I recently traded for this. I payed an Unusual Tough Stuff Muffs with Massed Flies + 20 keys (41.5-48 keys) for a Strange Unusual Tough Stuff Muffs.

I had bought the regular unusual for 21.5 keys in September, while the only other one on the market was listed for 28 keys. As of me writing this, there are two massed flies unusuals listed for 27 keys, which is still within a reasonable range of the 28 key price listed on this website. So, I'm assuming my offer was anywhere between 42-48 keys in value, as I bought my unusual for a good amount cheaper than the commonly found asking prices, yet most seem to be closer to the listed 28 keys than the price I paid.

I'm also aware of this hat selling on the Steam Community Market on September 22-24th of this year for $82-$83(about 46.5 keys), but am not sure how to show this, as I am not aware of how to get more detailed information from the SCM.

Been in the community for a long time, but never made any price suggestions before, I hope this was thorough enough.

Let me know if there is anything I could do better with formatting and/or evaluating price suggestions. Cheers!
