1972 Gibraltar 25 New Pence Question

Hello all,

I picked this up off ebay before my last trip and just opened it up today. I'm not 100% sure if it is the silver or the cupero-nickel version. It weighs 28.13 grams which is closer to the silver version. According to numista the silver version is 28.28 grams and the cupero-nickel is 28.47 grams. There isn't much wear. It has some really nice blue/gold toning as well. Any thoughts? I'm guessing it is probably the cupero-nickel version based on my luck Thanks for looking!

There is a difference in size.
Silver is 38.5 mm and the Copper-nickel is 38.61 mm.. can you measure it?

 

Unfortunately nothing to get that close

 

Or just try the old tissue test.. just follow the instructions

For the ones who have never heard of this, you take a bunch of coins flat on a table, cover them with tissue paper. Clads go DARK, and silver shines like a beacon

 

I just tried that with 2 64 Kennedys. 1 toned the other not. It looked just like your picture Unfortunately, the Gibraltar is a bit toned too so I don't know how well it will work. I may just have to take it with me next time I go to the LCS and see if they will measure it for me.

 

Yours is definitely copper nickel. You can tell by looking at it. That ain't silver.

 

I agree, it's Cu-Ni.

 

I agree with the rest of the members here. Your example is definitely cupero-nickel and not silver. I can easily tell by looking at the color, you will never find a silver example looking like that.
