Foam Ring Airtite Sizes for Australian Coins

December 9, 2008

When I was purchasing the foam ring insert type Airtites to house my coins I found that the sizes stated were all for US coins. They are only available to buy from America so this is understandable. I am in Australia and wanted to store my coins in these Airtite coin capsules so I had to do some research to determine which sizes fit best for Aussie coins. These are the results of my study:
  • Halfpenny -T 25
  • Penny -H 30
  • Threepence- A 16
  • Sixpence- A 19
  • Shilling -T 23
  • Florin -H 28
  • Crown- I 38
  • One cent- A 17
  • Two cent -T 21
  • 5c -A 19
  • 10c -T 23
  • 20c- H 28
  • 50c -H 31
  • $1 -T 24
  • $2 -T 20
For the majority I found that for the size of the coin in mm, you needed half to 1mm less for the size of the foam ring insert to hold the coin snugly.
