Just a tad loose for the Australian 1/2 ounce shark series, but I was glad to get them and fit the coins in.. They look great and won't get beat up in these holders. I will use them again when I need more items.

High quality coin capsules.

These coin holders fit the coins perfectly.

Very nice capsules, make the gold coins look even better

Better than plastic flips for handling, examining and protecting.

Wish there was an easy way to undo if I wanted to though...
