The expert shared: "Find these old coins and make big money... First we have the 1949 Brass Three Pence with a mintage of 464,000.
It can sell for anything between £9 and £700, depending on the condition. [Next] the 1905 Half Crown is from the UK, with only 166,008 ever made.
Later in the video, he talks about the rare 1853 Four Pence Grout, with a mere 11,880 in existence. According to him, even the poorest quality ones could bring in £230, rising up to £2,000.
He added: "Next we have the 1851 One Shilling with only 470,071 made, this can sell anywhere between £100 and £2,000.
The possibility of finding one of these elusive dimes among ordinary pocket change adds an element of intrigue and excitement to the pursuit of rare coin collecting.
And last but not least, the 1869 One Penny but we are not sure how many were made. Imagine finding this in great condition and bagging yourself £5,000, unbelievable."
