I understand that this most likely is plated, as I have found no information about any silver strikes. Its a 1952 New Zealand Penny, Silver in color. I attempted to get a decent photo of the rim, as there is what appears to be an attempt at reeding, and it looks pretty uniform. Sorry about the quality of pics, at work and limited resources    |

If you have - try comparing the ring sounds to another penny (or large copper coin with similar size) of the commonwealth (NZ, UK, Oz etc.) The sound difference should be significant if silver.
Do you have the weight of the coin?

I do not yet have the weight, will ask a friend to weigh it as soon as I can.
I just compared it to a British Penny from 1918 and it had a higher ping than the penny.

It has almost certainly been silver plated, perhaps in an attempt to make it resemble a halfcrown or florin.
I have seen several New Zealand copper coins that have been plated - I have a plated halfpenny sitting in my junk box.
Look for a spot - usually somewhere on the rim - where there's a gap in the plating, and the copper shows through. That's where they had to attach the electrodes.

Thanks Sap, So far no exposed copper found. The entire rim is silver, which throws me off.

Maybe it's my poor English skills, but was the ring of the 'silver' penny lower than the 'ordinary' penny or vice versa? I couldn't make that out entirely. Was the ring sound clear and long or was it 'stratchy'? I know copper-nickel coins can get that sometimes, that the ring sound is considerably lower than that of what it should be but the sound isn't quite clear and there are hints of another sound. Just my observations  |

If the planchet is of standard bronze penny dimensions, but struck in SILVER, it should
weigh 11.0 grammes, (+ -) about 0.2 of a gramme.
Almost certainly nickel or silver plated, weighing about 9.5 grammes, (+ -) about 0.2 of a gramme.

I may have an answer I can remember in highschool in the 1970s electroplating pennies as part of our chemistry class. They were cheap and easily obtained so I guess a lot of chemistry classes in NZ saw NZ copper pennies silver plated

Pretty much put the nail in the coffin by weighing it.
Came out to 9.4g on an inexact scale. No where near the 11g required if it was silver.
Its a good plate job at-least.
