Baker actually bought the VC on the premise it was a replica, but it was with Chards South Africa medal 1879 Bar. On his death the medal & the decoration (the VC is not a medal, its a decoration) were auctioned.
On aqquiring the VC the bidder (Lord Ashcroft) subjected it by meturalgy test, which did reveal it was from the Ingot supplied by Donnigton to Hancocks who produce the VC from this scource, reputably from a Chinese Gun, which proved beyond doubt it was the original (or replacement of course?).
As custodian of Chards VC is Lord Ashcroft, who paid "a competetive market price", rumoured to be around £600,000., as with all medals and decorations, you never own them, they belong to the recipient immortalised on the rear or rim.
Recently Bakers son was demanding the correct price for it, one would argue, the correct price was that paid when it sold as a replica, as Baker bought it, as a replica.
