Copper or gold color in poured silver cracks

[EdgarSilverman]

I recently bought a 3 oz Bison Bullion poured silver bar. It has the a coppery or goldish bright tone areas inside the bubbles seen on poured silver bottoms.

It looks bright like new metal not tarnish at all, I've included pics. I"ve also seen this color on vintage poured silver bars in the cracks. .

Also, the bubble holes are deep and some I can't see the bottom as they disappear into the void! I like bubbles, but normally all are relatively shallow compared to these.

Does anyone have info on the color and is the deep holes a concern for resale if i want to sell it down the line? 

thank you.

Errrr are you sure it isn't a fake bar and you are seeing the copper core,

It looks like that to me, but the pics aren't the best. It could be toning from the images but as you have the bar in hand you have ruled that out that only leaves a fake.

It looks fake to me, send it back and get a refund (best solution in my opinion).

I’ve seen this before, not with silver but iron. Impurities will cause gas pockets and can be quite violent when pouring.

Another explanation is the mould was cold, that’s even more fun! Molten metal on to water equals an explosion.

In this picture you can see a sample mould being “warmed” before a sample is poured. (bottom left)

Impossible for me to rule out fake without seeing it but I have some experience with this type of colour happening when you "antique" the silver. 

The chemical reaction makes it go all sorts of lovely rainbow colours before it settles in a nice black. On some pieces it could be the left over bits of the liver of sulphur that causes it.

Personally I am not immediately jumping to the conclusion this is a fair bar - as the colours I am seeing fit quite well into the liver of sulphur experience I have had.

Try getting some silver polish in those parts and see if it cleans up. Or, do a specific gravity test to be sure.

Thanks for all your responses so far...  Bison Bullion does antique their bars to give the black in the lines... thanks for the insight Backyard Bullion, 
on the sulfur color... I like your videos on youtube.. I know you'd never let one like this out of your shop being as meticulous as you are! 

Bison Bullion is a  big poured silver seller, and this one looks just like all the ones on their website... this one weighs 93.5 grams, just .2 gram over,
well within resolution error of the scale. I'm pretty sure it's real, looks & feels real and the weight is right. and the size is correct for a real one. 

I just bought it from a coin dealer on ebay that sells a lot of stuff and numismatic coins and has 100% feedback. He accepts returns, I could process a return.. I guess more than the color is the bottomless holes and dime size area is sort of slaggy...  I guess I'm not happy with it, he did have pictures but I thought the color was uncleaned flux or something. 

Does anyone think I would have a problem getting full price for it down the line? i'm wondering if anyone else would not be happy with this purchase too, or am I being to critical on this poured silver? 

thanks!

Not sure I would be happy with this bar.  Anytime there is a question mark over anything you are trying to sell, bar, coin or any other item, the resale price is going to be affected.

Looks like normal toning to me in the pits and if I saw this in my LCS I would not even question that coloring for a minute. If you are that worried about it test it with a sigma metalytics machine. I think you are fine. Who is really going to counterfeit bison bullion?

I’m going to go with 100% genuine. I’ve seen this type of thing on other bars before. As long as it really is real I’d be delighted with that. Looks cool!
