In a deal brokered by CPLG Sport, the Royal Mint has produced 150 limited edition gold medals commemorating the nPower Ashes Series 2009.
The first five of these were used in the coin-toss for each of the Test matches and are engraved with the relevant date and venue.
These are now being auctioned off for charity, with proceeds going to five ECB partner charities - Cricket Against Hunger, Chance to Shine, The Lord's Taverners, Prince's Trust and the PCA Benevolent Fund.
The auction is open until the end of September and can be accessed here.
"There is already great interest in this auction and the fact that England won the Ashes in the last game of the series is going to make these medals even more sought after," said CPLG Sport's Tom Roe.
