Wide Eye Variety

In John Cresswell’s book New Zealand Practical Guides : Collecting Coins and Medals 1973 there is a mention of a 1961 Halfpenny with large eyes on Tiki.  Notice the lines under the Tiki’s left (higher) eye are missing

One thing that has been noticed is a gap forms between the Head and Body on the wide eye variety but this gap also appears larger on other 1961 halfpennies
