AmE uses words such as "nickel", "dime", and "quarter" for small coins. In BrE the usual usage is "a 10-pence piece" or "a 10p piece" or simply "a 10p", for any coin below £1, "pound coin" and "two-pound coin". BrE did have specific words for a number of coins before decimalisation. Formal coin names such as "half crown" (2/6) and "florin" (2/-), as well as slang or familiar names such as "bob" (1/-) and "tanner" (6d) for pre-decimalization coins are still familiar to older BrE speakers but they are not used for modern coins. In older terms like "two-bob bit" (2/-) and "thrupenny bit" (3d), the word "bit" had common usage before decimalisation similar to that of "piece" today.
