I'm not sure why you closed this, I did say that it was perfectly fine

Having said that, there are now more sales:

https://gladiator.tf/listings/60821f2061649b1806772d2b - buyout 155 keys
155 keys leave buyers inventory and histories match so I think you can take this sale as 155 keys flat

I don't particularly know what your sale was.
Searing Plasma Crones matches history - https://backpack.tf/item/9978116026

And then the 155 key sale you already recorded.

155, 145, 150, 155

[b][u]Concluding thoughts from me again[/u][/b]
Your original suggestion was fine at the time since the 145 key purchase above had not happened yet.
Realistically, with the new information I've provided, I think 145 - 155 could work, but please wait for a price mod to comment. I'm not experienced enough with situations like this to call the right shot.
