Listing roughly translates as: You are bidding on here a silver coin 30 Dollars Elizabeth II Australian Koala Information to the coin: Quality: PP Front: see picture Back: see picture Size: about 15 mm Material: Silver Weight: 1 g A high, quality minted class. Get this classic, do not miss among the coins / bars.
Surprised they used that koala design - much better design years, ie 2009, 2010 etc. Back on topic... bad bad counterfeiters!!!
1 gram with a $30 face value! Didn't think about that much did they. Probably copied the obverse from a 1kg.
The seller also thinks that they are legit, Good quality restrike he tells me, I reminded him that copying Australian legal tender is fraud.
What terrible coins, their diameter is 15mm, about a shirt button size. I should use my new 60x microscope I bought to watch nano-technology coins to watch these too, LOL Alex.
