Pete Jackson, chair of local community project Cinderloo 1821, had organised the auction after finding the piece of concrete while walking with a friend on Sunday.
But, after it concluded he announced he would be giving it to the winning bidder for free because “Telford’s heritage should not be up for sale”. He said: “Over the past 200 years much of the industrial heritage of what is now Telford has been demolished.
“The cooling towers are the latest place of work and part of our landscape to be lost.”
The item’s description read “Ironbridge Power Station 100g Piece Of Concrete. Condition is Used.
“Found outside of demolish zone following the 4 towers coming down on 6th December 2019.”
