Since it's 1/1 and now I own it, I think I should suggest its price from what I got it for. 156.10$ on the Steam Market divided by 2.00$ (per key) 78.05 Keys worth. Since, I buy keys at 2.00$ I think it'd be worth it at that. However, apparently Backpack.tf uses a different method for keys on pricing. So I put it as 81 keys as the highest value. As for, 81 Keys apparently goes up to its closest other than going over the price I bought it for (BP.TF Key Priced).

(FIxed the mistake on the Non-Tradable suggestion Lmao)
