  "Hello! I recently bought this a a garage sale. Upon getting home, I realized it had a strange yellow hue. Can anyone confirm this is brass, or does bronze sometimes oxidize this color? Thanks!"

You've made 5 topics for the same question, you only need one. I have sent a note to staff. Your coin seem to be bronze.
Here are the specs for bronze and brass:
Brass: 25.75mm and 4.29g Bronze: 25.4mm and 4.54g
Perhaps there is an error on your scale giving you a value of 4.57g? It could also be a counterfeit but that doesn't make sense since a counterfeit would weigh less than regulation not more.

No one can tell from a pic online. you could try scratching the edge to see if the yellow colour continues beneath the surface, but that may damage the coin. You would need a reliable XRF test to be absolutely sure.

If the mass written on the flip is accurate, it's too heavy to be brass.

The brass coin weight of 4.29 grams is the weight of the ONE coin in the BOC museum,other brass coins may well be heavier or lighter than this one. The specified weight for ALL 1859 cents is 4.54 grams, whether brass or bronze (sorry there are no coppers). 4.29 grams is well within the Weight Tolerance for 1859 cents no matter what the composition. The OP's coin at 4.57 grams tells us nothing of the composition.

First off the seller of the coin knows full well it was not Brass..Why would he put all this info on the 2 x 2 .. My experience tells me he knows very well it was bronze, + coins has likely been cleaned ..... As for the edge test scratch a tiny line using a piece of glass...It will not react with the metal... I have done this on a super rare token and the brass will show yellow.. Bronze will show a reddish color..

By the way..  Quote: Bronze will show a reddish color.. you mean like the color I can plainly see coming through the fake coloring.

Colour is not a reliable indicator for deciphering bronze and brass. Research with various tokens and early provincial cents with Chris Faulkner and the Bank of Canada curators has proved this without doubt. Publications, with XRF data, will be forthcoming...

Sorry about the number of posts . I was getting an error message every time I tried to post this.
When I bought this, there was no 2x2, its my own writing. Is there any tests that could be conducted? If this is brass, it could be worth in the six digits?

If I had all six numbers on Wednesday night I would win lotto 6-49. No way your coin is brass.........don't dream submit it and show us all the results when it is back. My professional expertise says..............coin cleaned now retoning. You get this effect on US high grade Indian cents and to some degree on Large Cents. Dubious dealers and collectors in their need to enhance bronze and copper pieces strip them down and recolour them with different chemical concoctions. Sometimes it works and most often NOT!

Aren't there very well known and established "key markers" on the known brass cents ....and why not use these markers as a first step..?

There are no markers because these are alloy mixing errors, with planchets likely randomly mixed in the batch originally ordered from the Heaton Mint. Known brass coins have been struck by different dies.
