Should I Clean (Conserve) This One?

In another post, Earle42, made mention of porcupine quills as an alternative to the toothpick.

I haven't tried them yet, but my brother has some dogs that aren't very bright, so I should be able to get some if I'm patient.
Earle42's observation is that the quill is sharper than the toothpick, and is used to "scoop" the debris off the coin. I can appreciate that, as I usually sharpen the toothpick with a pen knife, and try to get underneath the crud and lift it off like I'm using a spatula. When I want something softer, I hammer the tip of the toothpick until the fibers separate and use it as a tiny brush. Fluid helps.
I've also heard that rose thorns can be used, but haven't tried them either.

For a more conventional application of Verti-Care, I selected a pair of Swedish 10 Ore coins.
The 1937, is perhaps in VF condition, but has some spots. Verdi-Care seemed to remove much of the crud, and I am happy to stop there.
Note: The after shot may appear lighter because of changes in lighting.

This Chinese 10 Cash from 1912, was an easy one. My primary goal was to remove crud.




Verti-Care was applied, and about an hour later, the crud almost floated off.
I rinsed the coin in acetone and filtered the results.



There are still a few crusty green spots, but it was easy and I'm happy with the results.

This is some beautiful work here. Good job






Remember to pick the one of least diameter. These can be pretty thin. My perfect sized one for reaching into the middle of a D mint mark finally gave out the other day... here porc-y, porc-y.
