Stamp sorting

another wet weather pursuit...friends and relatives collect stamps and postcards for me from their friends/family/offices...I am sorting into used /unused GB / Foreign .
Some I keep but most go to charities for kiloware to make money by weight and type.
I am a stamp, postcard and cover/mail collector. My covers are mainly foreign railway travelling post offices, wartime occupation mail, underpaid mail etc. Postcards are of steamer and steamer post from 1890s -about 1950s...since I retired this hobby is ideal for me in the winter
