I bought this the other day.

Realy nice coin but ruined numisticly by polishing.
I think I had my beer thinking cap on when I bought it

BUT it has given me an idea

This penny actualy looks realy nice ( a bit like rose gold)
I have a heap of "not so flash" pennys, enough to make a dansco set up (without the 1930 of course).
If I polished them up with brasso they would all look just like the 1925.
I won't do it to any nice pennys but the set would be something totally differant.
I havn't seen or heard of this being done yet.
After a few decades the coins should re tone anyway, so I wont be destroying any of our Aussi heritage.
