Is the 1988 Isle of Man commemorative coin pure silver?
I see 15 different designs of the Isle of Man Crown issued in 1988. Most of them are commemorating the bicentennial of Australia. All were issued as business strikes (but sold as collectables, not issued for use) and proofs in copper-nickel. Six were issued as 1 oz of .999 or .9999 silver, and one as an ounce of .999 gold. The ones that are precious metal are marked “1 Ounce Fine Silver (or Gold).
