Verdigone before and after. First pics are after NCS removed toning in attempt to remove the spots. This a follow-up to my previous post on NCS. I had used Dellar's Darkener on this coin and my S VDB to try to cover up the hairlines for better eye appeal. I have generally had good reactions with this product for hairlined coins. It does not look as natural but better in the short run for notedly hairlined coins. I was unaware that the sulfur in Dellars can coagulate and seperate from the petroleum= equals hot spots of sulfur which accelerate the reaction and caused black/grey spots. This happened and spoted this coin and my S VDB. I gave up on the VDB and sent to NCS to see what they can do. The Verdigone darkened this coin and made the hairlines calm down. Either that or the Dellars filled them in. Either way I am very pleased. I personally think this will grade again and I am sending to PCGS after it tones a little better in a paper flip or my album- haven't decided. If I had known about Verdigone I would have never screwed up the S VDB as I would have used it to remove the 3 verdigris spots instead of many hour soak in acetone. My coins aren't worthless, just worthless than they used to be. I can accept this. I am posting for everyone to learn from my mistakes and for Thad to get some props on his product. I am a believer
I don't know how to do more than 5 photos- I don't like use the hyperlinks. Anyways forgot to mention the first three photos have shiny look due to mineral oil. Tempting to reoil, but will let patina reform and then decide. About 5-6 NEW spots broke out from the Dellars in addition to the ones that were to the left of Lincolns face originally. Here are some more photos:
Nice coin but that's why they say to try anything new on a cheap no value coin , not a beauty like this . rzage
Looks better, but I was wondering, between the 3rd and 4th pics, did you use dellars darkener? I have tried it on a common date, cleaned IHC and it didn't make it look brown like that.
Yes, it was used from the 4th pic on. It was clumped up as I said so it over darkened it. I was advised after this happened, to mix Dellar's with vasoline to decrease sulfur content and mix well (like spun butter) to make sure the sulfur doesn't seperate like it did in this case which I was unaware that this could happen.
Ouch! Leadfoot: if I could undue what I did I would all day long. I would be very reticent to use Dellar's on any coin again. The only coins I will attempt to improve are the problem coins that I bought. I want to improve for myself. If I were to sell those coins I would disclose their history. You all know I have laid myself out on this site and been pretty transparent, I hope. Yes, I have played doctor on some coins- regretablly for the keys, and nonregrettably for the low value ones. Last night- I worked on this Fine grade 1897 IHC. Has vedigris all over it and some corrosion. Soaking for about 3 months in mineral oil. Used rose thorn and will do Verdigone when done. I have immense satisfaction working on a coin like that. It already looks better and not unnatural IMHO. Sorry, for long response.
I know you're heart's in the right place. I was just yanking your chain (thus the at the end). No disrespect (or flame war) intended.
The ultimate test would be to send it to PCGS or NGC and see what they do with it. In case you couldn't figure it out, I'm against doing anything that will change a coin's surfaces. One notable exception: Nic-a-date on cull Buffalos.
