can we please have an australian sovereign set?

ive seen peoplke ask on here before and they received! so here i go....i want somewhere to put my lovely sovereigns...there are other world coin sets and 3even some for australia but nothing for these fascinating coins with such a long long run....with the same sovereign being minted all over the world except for the mintmark its also something different...a half sovereign set would also be fantastic!...is this a possibility? who decides what gets a set and what doesnt? anyway thats my 2 cents...also hoping adding the silver eagle reverse of 07 coin to the registry in its own spot will see a rise in value for these little gems...i hope because i purchased my ms70 for $800!...i just had to have one!

anyway good luck to all in there collecting adventures
