Valuation / Catalog Reference
According to Albany Stamps, the ½d Silver Jubilee (normal watermark) in unmounted mint is priced around £26.50 for that single stamp.
A full mint set (½d, 1d, 1½d, 2½d) is offered by Commonwealth Stamps around £47.50.
The rare “Prussian Blue” 2½d variant (a famous error / rarity) has fetched thousands in auction.
Standard catalog listings (SG / Stanley Gibbons etc.) list these issues as common commemoratives; your blocks are multiples which can command a premium if in excellent condition.
Given your items are blocks of 4 for the ½d and 1d, with original gum and reasonable condition, a rough valuation might be in the range of £70 to £120 (or more) depending on quality, gum, and demand.
