A HOARDER who boasts the world’s biggest National Lottery scratchcard collection could have missed out on winning millions of pounds.

Dave Mannix, aged 42, hasn’t removed the silver films from 10,000 of his cards and almost all of these have now expired.

The avid collector has filled a room at his Widnes home with boxes containing a phenomenal 100,000 scratchcards.

He is now putting his extraordinary collection up for sale for £500,000.

Dave said: “I want to give someone else the chance to own this unique gathering. It’s taken half my life to build up and I want it to go to a good home.”

Dave has spent £80,000 over the last 20 years buying used and unscratched cards.

His obsession started when he was given a batch of 400 cards in 1994.

He said: “After that I went into a shop and I saw a container that was bulging with used scratch cards so I asked the woman behind the counter if I could have them.

“I asked a few different retailers if they could keep the used cards for me and all of a sudden my collection became enormous.”

Dave, whose severe arthritis prevents him from working, has complete sets of special edition cards from Indiana Jones to James Bond, Lord of the Rings and Star Wars.

Only one card has evaded him, the first scratchcard from 1994.

He added: “Apart from one I know of, I’m pretty sure I’ve managed to get hold of all the cards ever made and I’ve spent around £80,000 in doing so.

“I’ve got a designated room in my house where I keep them all in boxes so I know exactly which ones are where.”
