Here a few pics of a 1930 penny and how they can be aged to look older. There are heaps of ways to change a new coin to look older. You can Google this and it will give you heaps of different things that people do, I have heard of coffee all the way to dipping into nasty chemicals. So pic 1 is a new copy coin from china. The second type is after a dipping into something, dad dint tell me what but the first time it was light brown and the second dip turned it blackish brown as seen. It was only in the solution for a second so this stuff works super quick. The last one is one that dad made up, he didn't tell me what he did, but we put it outside for a month and it tarnished itself down to a completely natural tone.  |

They dont look to bad. Shame you don't know what is was he used. I have found boiling coins in distilled water and brown shoe polish fr about 2 hours gives a similar look but not as good.

The problem with accelerated ageing using chemicals is that you can't be entirely sure you've "switched it off". If you haven't thoroughly washed off all the chemical and deactivated the surface, you might have a realistic-looking artificial patina on it now, but come back in a few years and it might be thoroughly black, or covered in crumbly green verdigris.

The Royal Mint used sodium thiosulphate (photographic hypo) to darken Edwardian farthings to differentiate them from half sovereigns of the time.

It is. That's why the Chinese are mass-producing replicas of them. And Australia doesn't have an American-style Hobby Protection Act; replicas of predecimal coins don't need to be stamped "COPY" here.

I bought some 1930 (and 1937!) replicas from Hong Kong a few years ago. They were already 'aged' and had very nice looking toning.
As I recall they cost $7.50 each, including postage, and were not stamped "replica" as the advertisement suggested.
