Mexico 1 centavo, wrong colour

Pubblicazioni di 3 • visto 60 volte

G'day all!

I just found this N#5133 coin in my collection, but noticed something odd: it's the wrong colour!

 

Last time I checked, bronze coins were brown/redish, but this one is completely white. And since it's not plated, the bronze couldn't have been scrubbed off. I seqrched the catalogue if there's a nickel version I have missed, but found nothing. I've had it for years but don't know if I've gotten it in a swap or elsewhere. I've never seen a bronze coin go completely white without a trace of the original bronze. Any ideas?

 

Diameter: 19.5 mm

Weight: 5 grams in 2×2, so about 3 grams?

 

 

Cheers!

Yeah, maybe. Someone's done something, that's for sure. 😅
