Dallaglio is auctioning off medals, trophies and caps from his glittering career following a costly divorce last year.
The 54-year-old shone for England during their run to glory at the World Cup 23 years ago, culminating in their 20-17 final victory against Australia in Sydney.
The World Cup medal is listed with an estimate of between £50,000 and £80,000 by auctioneer Budds, with the whole collection having an estimated value of £180,000.
Budds lists 22 items in the 'Lawrence Dallaglio Collection', including a 2003 Six Nations winner's medal, other medals from his successful club career with Wasps and a British and Irish Lions cap.
Earlier this year, former England captain Dallaglio spoke about his financial difficulties during an appearance on the High Performance podcast.
"As a result of getting divorced, I was made bankrupt so I had some financial problems," he said.
"I could have done things a lot better."
Dallaglio said he needed therapy after his divorce and bankruptcy, which left him wallowing in "self-pity".
The auction will take place on October 13th in Northamptonshire.
