Mr Michael McCauley boasts 80,000 followers on TikTok under the handle coincollecting_detecting and frequently shares videos about rare coins.
The video McCauley posted two days ago has garnered a whopping 2 million views.
“Start looking through them for rare dates,” he said. “There’s plenty of things to look for.”
Coming across a 2004 20c coin, he explained that if the ‘A’ in Australia was particularly pointy, you could be looking at something that collectors would pay as much as $10 for.
He then came across a potential gold mine when he noticed a silver coin dating back to 1966.
He states that a small amount of the 20c coins from 1966 have a wavy baseline on the ‘2’,” and these coins sell for between “$250 and $4000 if you can find one.
For 20c coins minted in 2010, Mr McCauley said a bubble above the platypus’ claws also made it a valuable piece of metal.
McCauley revealed in the comments section that coin collectors on eBay will pay top dollar for rare coins such as these.
So if you have a jar of coins or a heavy wallet, time to start looking through them!
