i have been breaking up a massive accumulation of over 1 million gb stamps into lots of 100g which equates to approx . 2,000 stamps.each lot is obviously different but will contain a wide variety of definitives,christmas,non-xmas commemoratives,regionals,high values,postage dues etc.this is a great way to start a gb collection or a very cheap way to fill those gaps and to get better examples to improve the quality of your collection.p&p is £1.i have sold hundreds of gb mixtures over the last couple of years and have now topped the accumulation up with more stock representing even better value for money/
