Very nice conservation effort!
Coin flip or air-tite worthy!

Coin flip or air-tite worthy! Agreed smat - I think it more as a personal keepsake. Just a reminder, the "Oh Yeah, that was from .... " moment |

Holy cow batman! you could teach a class on conservation. I'm blown away. I think the reverse may give it away as being cleaned if it was looked at by a TPG and agree with Brandmeister on worn dies or weak strike which is pretty common. i'll call it AU (details) cleaned 1Step |

Man, I am going to send all my future metal detecting finds to you!
What is an alkali wash? I mean, I know what a base is, and I could Google it, but since you've got the conservation technique nailed, it would be interesting to learn.

What is an alkali wash? Haha, a purposefully generic term for an alkaline-based solution. I use Sodium Sesquicarbonate as the base at 1, 2.5, and sometimes 5% mix. pH is roughly 7.5, 8, and 9 respectively. I've found keeping the pH as close to neutral as possible to be key. You can run it hot or cold on silver alloys, I only do a cold wash on copper alloys which takes a bit longer. This one was done cold. I typically use it as my third option if VC does not perform as expected, or if experience dictates that Alkali should follow Acetone. Send me a PM, happy to share some write-up for future blog post on mixing and application. I'm just wrapping up conservation of a 1922 Peace that came out of the same spill - and is also a dramatic conservation. I whacked this one with my shovel which is truly unfortunate. Actually I'm devasted because it is high AU and has a die crack running rim to rim thru neck on Obverse. I also think this spill was unique - the soil was aerated/loamy. Almost like peat moss.

Thanks for the education! I have to say again, that is an extraordinary restoration. Do you think it would grade straight, or would a TPG detect the cleaning and frown upon it? |

Do you think it would grade straight Who knows on any given day. I've had a few conserved coins straight grade.I just had an Indian with the green patina (which is really super-mild verdigris) UNC DETAILS but only for ED, not for cleaning. A recent 1919-D SLQ that got an XF45. Acetone bath would remove any chemical indication of cleaning so solely visible cues. I don't see why this one would DETAILS. Here are updated shots after spot applying VC. If you didn't already know this coin's starting condition I think you would have a tough time convincing anyone it was cleaned/reclaimed/conserved or whatever.   Edited by DOCC

I totally get that. Fond of saying they could probably sniff a ground find coin and tell the date, time of day, and state it was dropped in. But at some point something has to give. All major TPGs have their own restoration/conservation departments. Coin dependent of course but I'll bet ya most output from in-house straights. Its like we all have to play these mob boss' games and pay their juice!
IMO the bottom line is, so what if a coin was conserved/cleaned/reclaimed. Does it have abrasions, darkening around devices, etc... then tag it CLEANED. But if someone brings a DOA coin back to life with no intentions of deceit, without obvious indications of cleaning, and does so with a focus on pure restoration back to originality, then shame on them for seeking out a reason to details.
