Did Sapphire Knife make money for release buyers?

Sapphire Knife sold out of its original stock 25 days after its first recorded sale, on Aug 1, 2023. Copies could be resold from Aug 6, 2023, once Roblox's 30-day resale lock ended.

For someone who bought at the original 150 Robux, the best return per day held came from reselling about 58 days after release, when copies were selling for around 700 Robux. That works out to roughly 200 Robux profit per copy after Roblox's cut.

Holding longer paid more in total: the most profitable point in its first year came 352 days after release, at about 475 Robux per copy.
