The BoA sale is going to be significantly lower here, and the person that paid this much is the one that resold it there.

https://backpack.tf/suggestion/5f5fbc58009a5e3fbc35bd51 sale on the BoA here is ~350, and he added ~200 for it, implying that his purchase is very likely an outlier.

New sales are also bulk:

https://backpack.tf/profiles/76561198109272505#!/compare/1602374400/1602460800 for a hearts stash

While the pan sale does not say much, the hearts stash sale definitely implies this is high as well.

Furthermore, there is a current marketplace seller for less than $499 available at the moment (listed for $475)

There is simply too much implying that this sale at $499 is the outlier here.
