Suggestion: Radiant Rivalry Antarctic Eyewear at 73–118 keys

Sold for a Sylicone Succiduous Bat Hat (63keys) + 55 keys (ID "13958519997" of the unusual matches, Bat Hat doesn't show up but that's because it was immediately dumped for 63 keys as seen by using ID "13958555129" of the Bat Hat in the buyer's side here which is what I'm taking it at even with the current suggestion open) = 118ish keys-

This wouldn't round given its below 100 keys

Taking 73-118 here :3

Sales 1 and 2 are both SCM; we know this to be true because the item enters the buyer's inventory as untradeable in both sales. The date range in sale 2's buyer compare link is a little too wide to comfortably call it, but sale 1 could be one of two sales from this link: https://steamcommunity.com/market/pricehistory/?appid=440&market_hash_name=Unusual%20Antarctic%20Eyewear . It's best not to try and guess.

This is a really long-winded way of saying- be on the lookout for when an unusual enters a buyer's inventory as untradeable, and if possible, try to parse it out.
