From Mindacos:

"Yeah I don't think this is gonna work out.

The 28 Key is on the old side and now is countered by buyers at 30+. The sellers at 50 Keys seem to counter your high-end as well.

I was originally going to say that this would be best left outdated, but thankfully we got a new sale:

Sold for $79.99 on Marketplace(~44 Keys using 1.83 value)

https://marketplace.tf/items/tf2/463;5;u3051

So this should be resuggested at 44 flat."
