About Casket
The Casket is a members-only item in Old School RuneScape.
"I hope there's treasure in it"
Over the last 30 days it traded between 666 and 883 gp on the Grand Exchange, averaging 740 gp. About 2,376 units changed hands per day. The price is up 12.7% across that window. The Grand Exchange buy limit is 50 every 4 hours. Selling one at the average price costs 14 gp in Grand Exchange tax.
Casting High Level Alchemy returns 30 gp, which is 95.9% below the 30-day average price, so alching a bought one loses money.
