Blackhawk

Were there any notable and collectible varieties of the British halfpenny minted from say 1950 till the end of their run in 1967? You don't hear much about these coins.

1953 has two varieties of obverse - one with cross pointing to bead and one with cross pointing between beads. Both are deemed common. There is also a proof that is very rare having the second obverse and a longer border teeth.

1954 has two reverse varieties, both very common. The second reverse has a thicker rim and longer teeth than the old Geroge VI reverse.

1956 has a number of minor varieties that get Brit sepcialists all twitted up.
Obverse 3 - "I" of GRATIA points to a border dot.
Obverse 4 - "I" of GRATIA points to the right of a border dot I of DEI points between two dots (as opposed to sightly left of dot in Obv 3)
Reverse C - Short border teeth, "L" of HALF points between two teeth.
Reverse D - Longer border teeth, "L" of HALF points to a border tooth. Still has calm sea
3+C - very common
3+D - quite rare
4+C - very rare
4+D - scarce

1957 has the scarcer calm sea variety as well as the common variety with the "rough sea."
Reverse E - rough sea.
3+D - common
3+E - ridiculously common

1958
Reverse F - slightly narrower rim than rev E, 21.2 mm ship width.
Reverse G - shorter border teeth again.
3+E is scarcest
3+F is common
3+G is very very common

1967 and 1970 have a thick rim and thin rim variety. Spinaker had some examples of the 1967. 1970 is getting some notice now.
