Understanding UK Coin Weights
UK coins have specific weight specifications set by the Royal Mint. The weights vary by denomination, with larger value coins generally (but not always) being heavier. For example, a £2 coin weighs 12.0g, while a 1p coin weighs 3.56g. Understanding coin weights helps with handling, shipping, and storage calculations.
Coin weights are important for various purposes: shipping companies need to know weights for postage calculations, banks use weights for coin counting machines, collectors track weights for authentication, and businesses calculate handling costs based on weight.
