100 1/2d & 1/2p stamps 50 each
Half Penny and Half Pence stamps, the change over from pre-decimal to decimal usage. You get 1/2p Queen Elizabeth II stamp in blue plus the 1/2d Queen Elizabeth II stamp in brown. Both have the portrait of the Queen on them and both are the lowest denomination stamps made of our Queen. You get half and half, so 100 stamps is 50 1/2d and 50 1/2p.
