It seems that there is a mess in the mintage section of the article
https://en.numista.com/catalogue/pieces2835.html
For example the proof 1963 is described as type 2 only by SCWC, being mintage given by Red book. But the Numista article gives:
1963 3,075,645 Proof (Type 1 reverse)
1963 22,164,000 Type 1 reverse
1963 Type 2 reverse
Most probably some lines should be merged.
In the case of 1963 it is expected:
1963 3,075,645 Proof (Type 2 reverse)
1963 22,164,000 Type 1 reverse
and so on for other years.
