Just heard an interview on ABC radio with coin dealer Andrew Crellin about the Holy Dollar and Dump . It's 200th Anniversary. Don't have a link to the interview ,but this will refresh the memory on how important this coinage was to the early development of the colony. http://www.coinworks.com.au/1813-Holey-Dollar-and-Dump.html
I think our local coin club is putting out a medallion to coincide with our 250th meeting. A good example just sold for a very tidy sum at auction, about $400,000 I think it went for.
