Convict love token, Australia,1792 - "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."
