Mods weren't big fans of just using buyers on my Uncraft madame dixie suggestion https://backpack.tf/suggestion/60a25c8ec35f275ff4355e64 which is probably the same scenario here, perhaps there's some valid sales in those history links, although most like TF2Mart which are rarely traceable.
Either or, there's still the new mp.tf which could be more of a solid data point than just buyers
Goodluck!
Forgot to respond to this before, but looking through all the histories you've provided, it seems all sales there are either >2 months old or between other trading sites - I suspect those older sales would be outdated anyway. The only one that seemed valid turned out to be a BP sale: https://backpack.tf/profiles/76561197996307844#!/compare/1616630400/1626652800 so bummer
MP sales seem high so going with buyer raise
Buyers at 5.44 since June: https://gladiator.tf/listings/60ce3a299a84d484e75089b7
up to 5.55: https://gladiator.tf/listings/60fc6e66e2cdf7b912a52612
up to present at 5.77: https://gladiator.tf/listings/6106eada69ec483b79f63251, taking that.
There's been a new mp.tf sale at $0.88 since this suggestion:
