Pure silver on it's own is apparently very resistant to tarnishing. Silver alloys are more susceptible to oxidation due to the copper component If this is indeed true, it makes sense to me. I've noticed that my sterling coins are mostly the ones that are demonstrating unappealing color changes. Very interesting. Here's an example of what I consider tarnish on a .999 silver coin.  |

Can't see what you are making reference to from those pics, as that piece looks good to me.... It is 1987, as I was in 7th grade in 1987, so it has had time to begin toning. And you are right, .925 will tone out often from the other 7.5% of the copper present.... I have seen some gold eagle 1/10th dimes lately list on ebay at $299 to start, about 100 over typical price. As they have a red huge tone and being .91675 would be because that copper present is responsible for that red toning.... Edited by Silverhawk74

oih82w8,
That's the area. What's irritating is the stain wasn't there when I bought it two years ago. The coin was unblemished, in near MS70 condition for 23 years until it was sold to me in the rain-soaked Pacific Northwest where I call home. I believe humidity is the culprit; but then again, maybe not, as we have a dehumidifier running in the vicinity of the coins. It's a mystery.

Jeff the 1902 is a tougher date seems like and I kinda like that black crescent moon, that is what I would call it, with a hint of orange....
I would consider a group slab with some other coins to save cost, and if it came back MS-65 or 66 it would still bring good money. There are some dark Gothic Edward Scissor-hand collectors out there that would like to have it, lol. I would take it, as it is a dark unique coin...

I was wondering if a coin will CONTINUE its toning coarse once it is sealed in the slabs, or could the plastic slab itself contain the properties which would cause further toning even with the coin being airtight sealed?

Not a dumb question at all, as I was wondering same exact thing. I assume they are, but like my dad says...."When you assume anything, you make a blank out of me an you", lol....

When I ran out of plastic tubes I took regular mailing envelopes (high sulfur content I guess) and put 20 in each env. They angled sort of like this - ////// - so the crescent toning came where silver was not in contact with silver. The end coins went completely black on one side. Some consider the look appealing. I do like colorful toned coins but these are not colorful. I have relegated them to the bullion part of my stash for when or if the SHTF. Quote:

Hawk . . Loved the movie, the coins not so much... Here's an example of what I consider nice colorful toning. The 52 Proof dime has been in the plastic holder since '62 when I bought '50 through '61 in 4 holders. It toned radically compared to the other coins in the holder. Perhaps since it is closest to the USMint sticker that was placed in the holders.    |

Jeff I agree as well, like comparing apples an oranges as that is one fantastic Roosevelt rainbow. Nice little early fifties coin collection, that is a great little set. The Ben 52 an 53 quarter have some nice golden toning, and the quarter around the date nice color. Also, the 1950 penny upper right hand corner has a nice red hue.... Due to the obvious medals used to make penny's, they can be a HIGHLY sought after high graded tone coin, penny or not. I see key date ones with a nice round colored rainbow that list for big money, an they are not to be underestimated for no silver or gold content, or just being a penny. The smart penny guys will come right along behind an scoop them up an say thank you very much, an do well when they pass them on down the road.... This one here is listed pretty low just under 30 bucks, looks great 1970 large date. I saw another sller with a small date one listed at 900 to start with similar toning an same 1970 date, an think it is this eller but it is just not listed right now. So they fluctuate big time in value.... http://www.ebay.com/itm/RAINBOW-197...em43adac46e3By the way Jeff, I saw a little glass like piece with coins sealed inside that reminded me of your set, as I was checking my local Pawn shops close to my house to see if they might have anything good in display cases to move. One guy I know pretty well had the piece I mention an it had a walking liberty, Barber quarter, Merc dime, Buffalo nickel, an Indian Head penny. Most just circulated, to fine or very good, not real nice examples, rubbed smooth so I past even though he wanted 30 for it, which seemed real fair. This guy does not put much out, he hoards like all of us, but he said he will get me what ever I am looking for, like 2012 eagles out the door 35, not to shabby..... The shop down the road from my house two blocks away has some grade-able merc dimes listed at 10 each, a half canister Roosevelt's silver dimes (12) at 80 bucks, and a roll of 24 listed at 150. Also some Kennedy silver halves twenty each, lol. High dollar stuff, decent Morgan 1886 50 bucks, a couple colored ASE, one so brown it an case it look like it may have been sitting in a smokers lounge.... The did have some Canadian old coins, many on sell for 2 to 8 bucks each, but I didn't even bother to look them over as they were not nice enough in condition to catch my eye. Oh yeah one of those small George Washington commemorative rounds with him standing by his horse, and it looks like half oz. size, but was in a hurry an did not ask about it or price..... Sorry to get off subject, but I also noticed the garage sale an estate sell signs are flying EVERYWHERE again. Never hurts to stop by in your route by these places when you have extra coin in pocket, as there is no telling what you may find, and you will never know if you never go.... Edited by Silverhawk74

You know Jeff, I've been thinking about your comment that you've moved your envelope toned Morgans to the bullion side of your collection. If your other coins are as nice as this 1902-O, which looks like MS64ish, you may want to think about flipping them and re-invest the funds into true bullion grade coins. I'll bet you could easily increase you bullion weight. Just a thought...

Ahhh, so people use certain processes to artificially tone coins. One brand (Mehgrig?) of coin holders and original gubmint commem holders were notorious for bullseye toning, and dealers would buy them to duplicate that toning. I'm still waiting for a definition of AT that will distinguish between the first owner and the dealer putting coins in the same holder. Obviously, the collector wasn't intentionally trying to tone coins, while the dealer was, but it's the same coins and the same holders, so how can they be distinguished? |

To get the rainbow colors, the coin has to oxidize in the presence of sulfur. The dealer in your scenario is intentionally toning over time, while artificial toning is typically something along the lines of forcing oxidation with various chemicals, heat, or exposure to bright light. I don't have any problems with intentionally duplicating a natural process, but forcing decades worth of oxidation in a matter of hours, days, or even weeks is cheating. Edited by Engineer

Cheating how? You still need to define how to tell the difference, using only the evidence of the coin itself. Like with grading, we don't know what's happened to the coin, we can only decide based on what it looks like today.
