Do you recall any buyout on the guy you bought this off?

Edit: https://prnt.sc/10nc61f, cheers Offline, buyout was 25 keys,

For collector's pro ks persian:

https://steamcommunity.com/market/listings/440/Collector's%20Professional%20Killstreak%20Persian%20Persuader/

Recent sale is 15 keys so really it could cap

Current seller for one is listed at 12.8 keys

https://prnt.sc/10nc85e - 6.3 key seller, bots at 6.6 keys

Taking sellers/sales

15 + 6.3 + 6 = 27.3 keys, would cap

With seller on SCM for the persian:

12.8 + 6.3 + 6 = 25.1 keys, so also caps

Could wait for a mod response but I would rather use sales on the Persian than buyers here

Thanks to OP, found the history of the Persian

Used here

I mean, with the sale at 20 keys, I am even more inclined to say that this should be resuggested at 25 keys flat

https://pastebin.com/35aigvTb - here's a pastebin of the above work, feel free to copy paste the RAW paste data into a new suggestion and do 25 keys flat
