Title 31 › SUBTITLE IV — MONEY › CHAPTER 51 — COINS AND CURRENCY › SUBCHAPTER II — GENERAL AUTHORITY › § 5113
The Treasury Secretary can set reasonable manufacturing tolerances for the size and weight rules for dollar, half‑dollar, quarter, and dime coins, except where a specification is a fixed limit. The 5‑cent coin’s weight can vary by up to 0.194 gram. The 1‑cent coin’s weight can vary by up to 0.13 gram. Any gold coin must contain the full weight of gold shown on the coin. The Treasury must keep records of the type, number, and weight of each batch of coins and test some coins from each batch to check the weights listed in section 5112(a). If tested coins don’t meet the required weight, the Secretary must either weigh every coin in the batch, mark and melt any that fail and cast them into bars for reminting, or may remelt the whole batch.
