Conservators Coin-cleaning Precision Pencil with 2-Tips
Seller's Note/ This Precision Pencil comes with both fiber glass and hard carbon tips. These will allow you to accurately remove crust and dirt from your coins and artifacts without damaging the patina. The fiberglass tip work great for cleaning typically mud/dirt-covered coins.The hard carbon tip, likewise, is a power house for removing harder encrustations. Little to no pressure needed and each works on damp or dry surfaces. The tips will dull with use but they can be easily be sharpened to a concise point with a nail file or sharp scalpel.
As presented in the photo, I used both tips on one of our Digger's Choice issues. My total time using the Precision Pencil was less than one half hour.
