1907 Barber Dime

I am confused about the corrosion part but probably right about it being cleaned since it is blast white. I don't know why if it is cleaned why the back has black toning. I actually Googled black toning and got a thread here. It talked about most silver tarnishes black because of it being left out in the area where there is sulfur. Maybe the black toning happened later after cleaning? I was thinking that anyhow, anything that looks a little unappealing gets the dreaded details grade. I thought it was AU details too. At first glass I thought XF details but than looking at the PCGS photograde I guess I did okay on the price with the other coins:

Huh, I took that just as silver oxide. If it was a color other than black, I think it would be considered more appealing. I was a little confused about it. The front is blast white with a couple black spots and the back has that black stuff on it. If it was dipped in silver cleaner, wouldn't it take care of that or do you think it happened after? Maybe an old cleaning? In all actuality toning is a type of corrosion and the last stage is black I heard. I don't know if that is true.

AU details, corroded.

"Blast White" is a designation saved for shimmering Mint State coins.

This coin has a gray AU appearance with signs of a cleaning.

Regarding the reverse, in all likelihood corroded and looks to be pitting of sorts in the upper areas of the wreath.

this is a $20 coin in a fair deal between two people IMO. If I were to really press for just this coin and I was not willing to hold out until I found a legit AU50 in the $60 to $75 price range, I would top out at $25.

Actually, I was thinking $20 and that was about the mode of other AU Details coins. The most people would pay is $30 for a scratched coin. Any coins over that amount didn't sell. Coins that were around $15 were significantly worse. Actually, any toning on a silver coin is a form of corrosion. I could see people paying as high as $25 since the coin is still more attractive than the the other "AU Details" coin if you don't mind the black silver oxide but no higher. So I would tend to agree with DSFreeworld but including shipping cost.

Of course I think it just depends on how attractive that corrosion is. Nobody would expect reddish brown or rainbow toned coins to come back in a details slab. Uneven black spots of silver oxide would. I realized the black silver oxide on the reverse would detract from the value of it when bidding.
