<p>[QUOTE="desertgem, post: 3444788, member: 15199"]On brushes, Kolinsky sable brushes are the softest fibers and Squirrel hair brushes second and both are intended for watercolor painting. They are expensive , but have least chance of damage. If you dip them into solvents , only 1/2 up the brush fibers and soft strokes. If the coin is really heavily coated, and a little rub is OK, Chinese Ox hair is OK for a slight pressure to loosen, but I like the bamboo skewers ( small ones for cheese cubes, etc at a 99 cent store), Put the tips into the acetone or whatever and let set for 24 hrs. Bamboo is very porous vertically, so the 'sticks' pick up and hole the solvent/ A little pressure on the stick on a scrap zincoln should cause the tip to bend, and its ready to try on your damaged coins. Use and discard as necessary through the process. Far better than rose thorns or other as they are not as porous. Do not use immediately on your 72DD, practice on pocket coins until you are familiar with it. Done right they still get slabbed normally with no detail. YMMV. IMO.
