The United States is the largest producer of Canadian coins and has a national shortage of $50 million worth of the coins.
The United Kingdom has a $30 million coin shortage.
Australian Treasurer Scott Morrison has promised to restore the national coin supply by January 2019, and the Government of Australia has committed to restore $1.5 million worth a year for five years.
But when the national shortage ends in December 2019, it could still take up to a year and a half for the coin to return to normal supply.
“I think the coin shortage is probably over now,” Australian Bank of Commerce economist Ian Crozier said.
“It’s very likely that the shortage is about to end.”
He said it was possible the price of the $50,000 coin could increase over the next few months as consumers rushed to buy more coins.
“I can see some increase in the prices, but it’s not likely to be dramatic,” Mr Croziers said.
Mr Croziere said the Government had committed to restoring $1 million worth each year until December 2019.
“That is going to be very significant, and it’s going to bring the price back to normal,” he said.
Mr Morrison said he expected the shortage to end in November 2019, but he did not give an exact date.
“We’ve said that the coins will be back in normal supply by December 2019,” he told the ABC’s 7.30 program.
“The coins are not back in regular supply, they’re back in a special reserve,” he added.
“They’re going to continue to be in that reserve until January 2019.”‘
The best way to buy a coin is through a coin swap’The Government has also committed to making the coin swap available to the public for $1,000.
The Australian Bank’s Mr Croosier said the swap was a good way to acquire the coins, which had historically sold for a premium to buy them.
“If you’ve got a $1 coin and you’re looking to get it for $50 you can get it from the swap website for $100,” he explained.
“You can’t get it by the old way of buying the coin at a dealer, you can’t do that.”
The Reserve Bank of Australia said it would also continue to issue coins for $10 each, with a maximum of $100 per transaction.
But some customers are still struggling to find a way to spend the $10 coin.
“A lot of people are saying, ‘I can’t even afford to buy my own coins’ so I’ve got to get them on the exchange,” Mr Brown said.
