thinking for a minute, and people talking about the gold colour

that i believe is the copper content,

i was getting this reserached

apparantly it IS copper, just out of a type that is this colour. (it is also first batch from mother coin )

might explain this one

Bronze is always yellower than copper, I think that's explanation enough?

yea, depends on the copper ore though, the yellow type accounts for most of the worlds copper deposits, a change in the copper source to a diffetant chemical makup of copper (aka swedens more red type) would account for the colour.

That bottom penny is a ringer for the two brassy ones I had! I think they are troublesome from a collection point of view, as they really stand out like sore thumbs!

Almost as 'brassy' as this one (which actually is brass):

I recently came across a yellow 1864 penny. Unusual as all the other ones I've seen have been black:-

i have one of those, do find the odd 1861 and 61.

I picked up a light brown 92 as well, only seen that on 93's
