I'll try the verdi-care. Have you tried to develop a substitute for blue ribon?

[BadThad]

Honestly, I've never tried blue ribbon. I believe it was nothing more than a light mineral oil with some detergent cleaners. I have no plans to develop a such coin cleaning product.

 

Thanks for trying VC! Let me know how you like it.

I used it on several coins that looked like the one you showed in the picture above. This really works!!!!!!!!!!!!!!
