Monopoly, the third-most popular board game after chess and draughts, has sold over 275 million copies since its invention in the early 20th century. As the game celebrates its 90th anniversary, experts suggest that rare editions gathering dust in attics across the UK could be worth hundreds or even thousands of pounds.
First published by US firm Parker Brothers, Monopoly was licensed to Leeds-based Waddingtons, which created the version with UK place names familiar today. Over the years, numerous special editions have been produced, including a World War II set used by British intelligence to smuggle escape tools to prisoners of war. Such rare sets are highly sought after by collectors.
Kayleigh Davies of auction website Auctionet explained: 'Monopoly isn't just a game, it's part of popular culture, and remains largely unchanged in its 90-year history. This positively affects its status as a collectible, and luxury editions of the game can fetch a high price.'
One valuable edition is the Franklin Mint Collector's Edition, housed in a mahogany box with gold-coloured playing pieces. Good examples sell for between £300 and £400, while a set with the original game table and certificate of authenticity fetched £1,841 at auction in 2023. Even the glass protector alone sold on eBay for over $100 this month.
Other limited editions include the East Grinstead edition, featuring gold playing pieces, with only seven made and rumoured to have sold for £2,000 in 2020. World War II sets, which used a spinner instead of dice due to wartime shortages, often sell for over £40, with one reaching £70 on eBay earlier this year.
To determine if a family set is valuable, collectors should check its age and condition. Older versions in good condition with original receipts or dated packaging are particularly prized. 'With board games, collectability is related to originality, unique components, cult followings or links to media franchises,' Davies added.
