they wouldn't have been a holey dollar or dump. They were made from a Spanish 8 reale coin which is silver. I got to see both these coins in the flesh a couple of weeks back. We had a display brought through Dubbo by the State Library, celebrating 200 years since the start of Governor Macquaries Governorship. These coins were created by order of Gov Macquarie. Circulated from 1813 to 1822 when they were recalled from circulation. The only places of white settlement at that time were parts of Sydney, Bathurst, Tasmania and Norfolk Island; so if you want to find them, you need to hunt in those places.
There is not many of them left. The curator said that if you have one in good condition, then there are worth around $100 000!
The dump is about the size of a sixpence. It has the British crown on one side with the date of 1813 under it ( I don't know which country stamped that on, but assume that it was done here which means that they should all have the same date. On the back, it looks more like a token, with only the words, fifteen pence on it and no other decoration.
The holy Dollar, is a large coin with at best guess, approximately an inch and three quarters in size. The hole that the dump is punched out of, is slightly off centre and has in very small print around the hole, five shillings. The coins most likely have variations in dates and as they arrived in the colony in November 1812, they won't be newer than that. ( I just looked in the Rennkins coin book and noticed that the date of 1813 is stamped on the edge of the inner hole on the same side as the words five shillings.(Photo on page 9.)
That fellow that found a number of Gold sovereigns is one fortunate chap. Most of us will never recover one, but a bit of research and good luck can change that.
I'll be packing a detector with me when I go there, but I don't know how much of a chance I'll get to use it.I'll try and get at least one hunt in.
