https://marketplace.tf/items/tf2/6522;6;td-393 - new sale at $60 (33 keys)

i'd include 26.1 in the range here as i've been noticing that 27 key buyer has been disappearing and reappearing suggesting inactivity or low amount of keys so quite often the listing is hidden so i don't think it's been completely active the whole 2 months.

also scm sellers at 27 - 28~ keys atm.

you can probably round this to the nearest whole key given the mean is 30~ keys (26 - 34 keys)
