The British decimal ten pence (10p) coin - often pronounced ten pee - is a unit of currency equaling ten one-hundredths of a pound sterling.
The coin was first issued in 1968 before the currency was decimalised, to circulate in parallel with the florin (two shillings) coin it eventually replaced. Its dimensions were the same as those of the florin, and the florin remained current after 1970, re-denominated as ten new pence.
After a review of the United Kingdom coinage in 1987, the Government announced its intention to issue a smaller 10p coin, which was first issued on 30 September 1992. The original (large) version of the ten pence coin was demonetised in 1993 together with the florin and replaced with the smaller version, which retained the original design by Christopher Ironside.
All circulation ten pence coins for 1992 were minted to the new standard. However, the uncirculated and proof mint sets issued this year had both the old and the new 10 pence pieces (78,421 brilliant uncirculated, 44,337 proofs in the standard set and 17,989 in a red leather case).
Additionally, a small silver set was issued with both sizes in silver, listed in Spink with mintage "unknown" and in Krause as 35,000.
