London ( CNN ) -- Six months ago , a winning ticket was bought for the Euromillions lottery draw in or near the English town of Stevenage , north of London . But the jackpot -- a sizable £63.8 million ( $ 103 million ) -- has never been claimed . And whoever holds the golden ticket has only until 11 p.m. ( 6 p.m . ET ) Wednesday to claim their prize , or the whole sum will go to charity . The search for the unknown winner has gripped the centuries-old town of 84,000 , as well as the smaller neighboring town of Hitchin . Euromillions , which said the ticket was bought in the Stevenage and Hitchin area , has made repeated appeals to try to find the missing ticket-holder . A billboard campaign has even been run in a central square in Hitchin , an old market town . Whoever it was matched all five numbers , 5 , 11 , 22 , 34 and 40 , and the Lucky Star numbers -- 9 and 11 -- in the Friday , June 8 , draw . A Euromillions press statement attempts to jog the memory of the ticket holder , who it suggests may have come from the area or stopped off while driving through . `` Britain was gripped by Olympics fever , with the Games just seven weeks away , and the Queen 's birthday celebrations had seen the Royal Flotilla on the River Thames just the weekend before , '' it says . CNN 's Richard Allen Greene and Laura Smith-Spark contributed to this report .
The winning ticket was bought in the Stevenage and Hitchin area , north of London . The ticket - holder has only minutes left to claim a $ 1 million jackpot . The money will go to charitable causes if left unclaimed . The draw was made on June 8 , soon after Queen Elizabeth II 's golden jubilee celebrations .
