The 1919 is way too far gone.
The 46 looks OK as is.

That 1919 has been at ground zero of quite a few atomic bomb blasts, but it's still a scarce coin.

I do have some great coins in what I feel is "very fine" condition. I'm hoping that if I'm careful in the cleaning process, these will retain their value when I sell those that I don't need.

I would soak the 1919 in Olive Oil for a few Months.

Any chance of a Pic. of the Obverse?

You did a great job using these time proven techniques in conserving a coin that would have been a junker. I would continue with the Olive oil bath until all the verdigris is removed and then try a toothpick on the stubborn areas. After that leave it on the windowsill for a few weeks, turning every few days and the lightened areas should re-tone nicely.

Thanks Aero,what a shame,great eg.of a 1919 DD before the green stuff started eating it away.
I had a similar one that was in a Tobacco Tin I purchased off ebay a few years back,genuine seller that actually found the Tin in his Fathers garage.
After a couple of Months in Olive Oil I stopped the Verdi.growing but the Coin was stuffed,heavily pitted under the Verdi.,unfortunately yours will probably be the same but you have to at least try to save it.
