Look at it this way. On average, a Raccoon Mask cost around 100m with the scroll costing a negligible amount. Assuming it takes on average 3 to get it to pass, you'll spend a total of around 300. Add in resale deterioration and market demand and you get around 250-300. You might sell it for higher, but if people thought about it deeply, they'd know they'd be better off making their own.
