It just tells you the mintage figures for 2008 to present, but it says 22,747,000. I got that from here - http://www.royalmint.com/discover/uk-coins/coin-design-and-specifications/fifty-pence-coin You can click into each coin for mintage numbers. Another good source, although it doesn't mention mintage figures for the Matthew Dent design, is http://en.wikipedia.org/wiki/Fifty_pence_%28British_coin%29.
