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!
