Smoothing and engraving a coin with a message of affection was one of the few ways a convict transported to Australia could leave a memento behind with loved ones in England. These small tokens are also known as 'leaden hearts'.
Token, 1818 | Museum of London "Convicts sentenced to transportation to Australia often gave their loved ones tokens as keepsakes. These are also known as 'leaden hearts'. Typically tokens were made by rubbing a coin and then engraving or stippling pictures and personal messages onto the smooth surface. The tradition of giving love tokens originated with sailors who left tokens for their sweethearts."
