The first prize-winning ticket, which was issued in Jersey for the first time in seven years, is worth £483,795.
The second prize of £50,000 – which was issued in Guernsey – is also yet to be claimed.
Jon Taylor, Head of Lottery for States of Guernsey, said: “Both the first and second prizes have yet to be claimed.
“I urge participants to double-check their tickets. Participants have 12 months to claim their prize.
“After this period, the funds are disbursed to worthy causes and charities through the Social Investment Fund in Guernsey and the Jersey Community Foundation and Association of Jersey Charities in Jersey.”
