We imagine that everyone who buys a ticket in the British National Lottery or the European prize draw (or any other lottery for that matter) would keep it safe and carefully check it against the winning numbers in the draw but it seems that is not necessarily the case.
Two reports have emerged this week of lottery winners who do not appear to have realised there is money waiting for them.
The Belfast Telegraph reports a prize of £92,991 from the British National Lottery has yet to be claimed. The ticket was bought in Newtownabbey on 17 April but nobody has come forward.
If this situation continues until October this year, the money will be passed to one of the many good causes supported by the lottery.
At the same time, the This Is South Wales website revealed that a Millionaire Raffle ticket from the 16 April European prize draw has not been claimed.
The £1 million prize would change a life considerably. It is possible the winner checked the main draw numbers but forgot they could be eligible for a prize through the related Millionaire Raffle.
Again, the prize has to be claimed by October or it will be lost and passed to charity.
If you live in these areas and still have your old tickets, please check them again: otherwise search the house to see if you have mislaid a ticket. It might be well worth your while!
