All British Halfcrown coins from 1816 up to and including 1919 were made from sterling silver or .925 fineness.
Please look at the coin again. No authentic 1816 U.S. one dollar coins exist.
From 1816 to 1919 inclusive, British Shillings were minted from 0.925 fine silver. The only exception to this was a Proof in gold FDC Shilling in 1816 which is so rare it is unlikely to exist outside of a museum. If you do have a gold 1860 Shilling, it is because somebody has plated it, rendering it worthless as a collectible.
If it is damaged, probably only the value of the silver. Your coin could be a - Halfcrown - sterling silver, 32mm in diameter. Shilling - sterling silver, 23.5mm in diameter. Sixpence - sterling silver, 19mm in diameter. The diameter and the details of the inscription on the reverse would be helpful in identifying your coin.
The U.S. did not make any dollar coins dated 1816. From your description, it's a silver round not a genuine coin. Value is about $19.00.
It would depend on which "Pence" you refer to. The British Penny and Halfpenny were made from bronze from 1860 to their last minting in 1967. The British Threepence and Sixpence were made from sterling silver from 1816 to 1920, and from 1920 to 1946, they were made from 50% silver.
The first U.S. silver certificates were issued in 1862. Please check again and post a new question.
