A very rare and elusive 1868 Snow-13 with the reverse die gouge and a minor RPD. One of the most exciting cherrypicks I have even pulled off from ebay. What do you think PCGS will grade it as? Thanks for taking the time to look, Eric   |

Drew, do you think Verdicare or Acetone would help?

I wouldn't touch it. There does not seem to be anything "active" happening on the coin's surface, just a bit of crud, and successful removal of that crud will almost certainly result in surfaces differing in color from the rest of the coin being exposed. That means a coin which has obviously been cleaned. The color is off, but I cannot get a feel for what the original color should be. Assuming it was shot on a white background, the pinkish hue to that background says we're not seeing the coin's true color. As per usual habit, I downloaded one of the images and opened it in the Gimp to see if I could correct the color. The only color channel adjustment which had any effect on the coin was the Red channel, and experience tells me that when I can't alter the image's appearance at all by changing the Yellow channel, there are White Balance issues beyond easy postprocessing correction. By the time I remove enough Red to correct the background, the coin has no color at all. Any alteration would be a sheer guess as to appropriate color. I agree with Drew on the technical merit being in the F15 range. But to me, no conclusion regarding surface originality is possible from these images. |

I think there was some dirt on the coin before which resulted in that reddish clayish color you are seeing. Tonight I can try to post some more pictures from afar and upclose to try and get the most accurate color represented as possible. |

Use a white background, and let that tell you if you have the color right or not. Monitors are calibrated differently - regardless of what "color" you see on yours, it might look different on mine anyway - but white, being the "absence" of color, is the best way to find a common ground. If I know you're using a white background, all I have to do is make it white on my monitor and I'll know I have the actual color of the coin. |

The "white" is still plainly tinted red, which means the coin is too. What sort of camera are you using? We gotta figure out what we can do to affect White Balance settings and get your color closer to true. The images themselves are pretty good for sharpness; we can draw reasonable grading conclusions from them if we get the color right.

looks about f15 and does not look cleaned to me.
IN NECESSARIIS UNITAS - IN DUBIIS LIBERTAS - IN OMNIBUS CARITAS THE MAN IN THE ARENA, Theodore Roosevelt at the Sorbonne Paris on April 23, 1910: " It is not the critic who counts; not the man who points out how the strong man stumbles or where the doer of deeds could have done better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, because there is no effort without error or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself in a worthy cause; who, at the best, knows, in the end, the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat."

Fine details ED. To me that reddish area above the "ONE" and into the shield looks to be corrosion. The black gunk around 11:00 on the reverse may come off with a toothpick.

F-15 and I think Verdi-care would probably help it. That's a pretty cool variety!

Dave, I am using an iPhone 7Plus Camera with a Camerara Macro Lense Attached. I am using a regular desk light with a regular light bulb. Quote:

Are there other light sources hitting the coin besides just the one bulb? Even the monitor maybe? Light of differing color temperatures hitting the sensor at the same time can confuse white balance correction. |
