Coin Cleaning

Before cleaning/conserving coins read up on the process fully. As a general rule do not clean coins.

If I have a valuable modern coin, it goes into an acryllic screw capsule; I don't use slabs, they don't suit my storage system. Slabs are doubly useful if you wish to sell them, the implied guarantee for authenticity is as good as the business that graded the coin.

I don't use Verdicare, but I believe this product is probably the best for it's nominated application that is available; a lot of encouragingly good results of it's use have been posted on this Forum. Don't use on every coin, (wasteful), only those where you may feel that the use of this product is justified. Follow directions.

Distilled water and acetone are both powerful solvents, water for the removal of non organic matter, and acetone for the removal of organic matter, but both are pretty much useless for the cleaning of ancient coins recovered from burial.
A MUCH more sophisticated approach is required for the cleaning of ancient coins. Google various sites to read up on this subject. This work is usually done by professionals before ancient coins find their way to the market place anyway.

The inclusion of small silica gel packets with your coins would be of benefit in a humid environment, such as found in the coastal regions of the Gulf States. I don't use PVC album pages or flips, or paper products of any kind for coin storage, although acid and chlorine free paper products are OK.

for bronze coins, I soak in distilled water (some use olive oil..i also do occasionally), use a tooth brush and needle (start with a toothpick and practice), bake them in an oven when done to remove moisture (220 for 22 minutes).
I also use Verdi-care, but not so much for cleaning as the treating of bronze disease.
