To be fair about the weight and diameter, there are over 200 1 Dollar coins with those values.
Yes I do know about those 200 Australian 1 Dollar coins because I added about 95% of them to Numista. 😁
They are all Perth Mint coins. You can thank me later. 😏
There are also over 400 Australian 1 Dollar coins (Aluminium-bronze 25mm) issued by the Royal Australian Mint on Numista. (I added most of them too.)
But the issue is that Numismaster not only can not see or tell the difference between a Perth Mint oversized $1 Australian coin and a standard sized Royal Australian Mint $1 coin but they then label them as from the Peru Mint? Really?
Just for the record this is the size comparison between a Perth Mint Aluminium-bronze $1 coin and a RAM Aluminium-bronze $1 coin.

When you see them in the flesh they are very different. Both are perfectly legal tender here in Australia, but you will never find a Perth Mint $1 coin in circulation. They are only issued as NCLT.
For Numismaster to mis-label a RAM $1 coin as if it was a Perth Mint $1 coin and then list it as made by the Peru Mint shows a lack of creditability on their part. They need to remove the Master part from their name.
Anyway that is my bitch/rant over. Sorry if I come across as being a bit tough on them. Another member on here has given me a contact there to see if we can get things sorted out.
