1866 Isabel 4 Peso Gold (Spanish-Philippines)

Pandesalapi @ FYI: PCGS has graded another 1867 4P which is higher . It was graded AU55. Total Population for 1867 4p Isabel Gold is now 2.

1861-1868 4 Peso Isabel thickness? Need help with dimensions of the 4 Peso Isabel.

I hope it's ok to bump old threads, but this looked the most appropriate to post. I am in US, but bought an 1863 4 Peso Isabel on-line in Philippines as a gift and had it sent directly to my friend in Philippines. I wish to purchase a bezel for mounting into a necklace since it is a piece with some wear on it already.

Best I can tell the diameter is either 21 or 22 mm, and the thickness is approximately 1 mm. Bezels fit very tight, especially with thickness. My friend does not have the resources to measure thickness accurately.

Can anyone on the forum who owns one of these tell me what is the thickness of these coins?

Thanks!
