The $1 Coin That Could Make You $3000
A printing error that led to a distinctive marking on a series of $1 coins could see owners pocket a cool $3,000.
According to the Australian Coin Collecting Blog, a mistake at the Mint in 2000 caused a unique "double rim" on the coins that have since been nicknamed "$1/ 10c mules".
"Check the date," the ACCB say. "It needs to be a year 2000-dated $1 coin. Then you need to look closely at the circular rim of the coin - is it thicker than usual on the Queen side, appearing doubled?
"If you think that's the case then you might have a coin worth $1000 or more. The value of your rare coin will now depend on the condition.
"After spending 17 years in circulation, some coins are more valuable than others."
It all apparently came about "when a technician at the Mint in Canberra accidentally paired the mob of 'roos dollar reverse with the Queen's head obverse normally used for the 10c piece", the blog explains; the slightly different sizes in each coin side led to the thicker double rim that collectors are now going crazy for.
" was the height of the 'mule' season, with enthusiastic searchers finding one or more mules each day spent search," the ACCB continue. "With the mules fetching several hundred dollars each at the time, it was a profitable and enjoyable way of spending a day.
"Mules are still out there to be found by those willing to look."
Over the last 12 months, auction prices for the rare coins have ranged from $400 to $2700; if you do happen to find yourself a special $1 coin when you're digging through the swear jar, the ACCB recommend doing your research and checking out recent sale prices to make sure you're getting the right bang for your buck.
Pun fully intended, by the way.
