2007 Australian Twenty Cent Coin Set - THICK and THIN 7 VARIETY SET
2007 Australian 20 Cent Coin Set, the THICK and THIN 7 VARIETIES.
Looking at the pictures, you can clearly see that in this year, 2 different versions (or varieties) of the 20 cent coin were minted, the Thick and Thin "7" (the thin "7" is imaged first, with the thick second).
42.7 million minted, with no numbers available for the two different varieties.
Each set is in a similar grade to the imaged coins, and I have endeavoured to keep aside the best I can find. I would grade each set as Extremely Fine.
