Rare Australian 20cent coin worth THOUSANDS because of simple mistake

A coin enthusiast has revealed how Aussies can make $4,000 off a rare 20c coin.

Michael McCauley, from Victoria, has urged everyone to check their pockets for coins that have rare markings which could in turn earn them thousands.

In a TikTok that received more than 2million views, Mr McCauley said some 20c coins from 1966 had a ‘wavy baseline’ on the number 2.

‘It looks a bit like a cursive 2,’ he said.

Michael McCauley, from Victoria, has urged everyone to check their pockets for coins that have rare markings which could in turn earn them thousands. He says 1966 coins that have a ‘wavy baseline’ on the number 2 can be worth up to $4,000 (pictured is flat baseline on 2)

‘$250 to $4,000 if you can find that, I’ve been lucky enough to find two of those over the years.’

He also noted that 20c coins dating back to 2004 were considered valuable if they had a ‘pointy A’ in the word Australia, instead of a flat top.

While these are worth a lot less than the highly sought after pieces from 1966, Mr McCauley said they could still earn you $10.

Another feature to look out for is on a 2010 coin.

The expert said coins with a small bubble above the platypus’ right claw would be worth a lot more than 20c.

Coins with that marking are currently selling on eBay for $55.

Mr McCauley has racked up more than 82,000 followers on TikTok for his detailed videos into rare coins.

His tip to Aussies is to keep an eye out for rare dates and to try their luck and sell them online to other coin collectors.
