The first couple of annuals are hard to find in anything approaching decent shape. The later annuals are all very common and of no real value beyond a couple of quid. There was also a 1962 Look and Learn Book for Girls at roughly the same value as the Boys Book. Also came with a dust-jacket.
Note: Wonders of Nature (1968 to 1972 – like the 1,001 Questions, the first Wonders of Nature appeared in late 1967 and copyright that year), Young Scientist (1970-1971: there may be more but I don’t have them), Book of Pets (1970-1974: there may be one before 1970 but I haven’t got it), Railway Wonders of the World (1974 and perhaps more scarce) and Speed & Power (1978. The 1979 edition was larger size to normal annuals. Has No. 1 on the cover though no more appeared after that. There’s an Arthur C. Clarke story inside from 1949 with full colour art by Ron Embleton. Nice!).
Note: some PR issues may have no value. Selected issues in FN, VF or VF/NM may not exist in some titles.
