Should I use werdi-care on my BU wheaties (i.e. relatively problem-free coins)?

I see posts showing the use of verdi-care to remove verdi gris. What about using it as a 'pre-treatment' on coins with relatively no problems (i.e. BU wheaties, and coins from us mint and proof sets? I apologize if this has been addressed elsewhere.

If it ain't broke, don't fix it.

 

Figured that is what most would say - and I tend to think this as well.

However, I have a hard time believing that the BU wheaties are not broken at some level inherent to the coin and the reactive nature of copper. But, I take it nobody does this as a conservation step - sort of analogous to waxing a car to keep the paint job protected. :yes:

 

If stored properly, they should not deteriorate in a way that you fear.

 

That is normal preservation for an automobile paint job, where as it is not for coins. Otherwise an acrylic plastic coating would do even better at protection, but would never satisfy a coin collector. BU coins fresh from the mint have already started reacting with the environment causing a thin acceptable patina to form. If the coin is kept from moisture, plasticizers, and tainted air, the patina should protect it for a lifetime or more. With the normal conditions, enough reaction can occur to change the coin from Red to Red-brown to Brown, so if one wants to protect against that, my recommendations would be to store in a vacuum, or store with desiccants and bright copper sacrificial cents (cheap),
or with Intercept products ( relatively expensive). Desiccants, sacrificial cents, and intercept products have to be changed over time as their reactants are used up.

The inexperienced who, often with good intentions, attempt to improve coins usually end up causing more harm than good. Desertgem gave you good info, but if you want to experiment, that is both fine and one of the best ways to learn. Just don't use any coins of real value.
