This wasn't an easy one to find information about! It turns out to bear the heart-shaped design of a merchant's mark, or 'bale mark', used by the British East India Company in the late 18th century. Such a token would identify a unit of goods as belonging to the East India Company, such that they could be successfully recovered and ownership proven after transport from India to Great Britain. These coins or tokens were produced in numbers that seemingly allowed them to also circulate as coinage, with the bale mark image of the East Indian Company on the coin as a sort of official seal of approval. Genuine larger 1 pice coins weigh around 9.65 grams, while the tiny one-tenth pice coins only weigh 0.9 to 1 gram. These coins were minted in Calcutta, India. If your coin has no date and only one side has a design (the EIC inside the heart standing for East India Company), then it was minted in 1786. Coins with only one side struck are known as 'uniface' coins.
