Handling Coins
- Always be held between the thumb and index finger, with those fingers only touching the edge.
- Have clean hands or wear cotton gloves if you have moist hands
- Don’t eat around coins.

Magnification
- General grading 5x to 7x
-Error and variety used 10x or 15x - Hold the glass near your eye at a comfortable distance and bring the coin toward you until it comes into focus and keep both eyes open for easier focusing.

Housing Your Coins
- 2x2 Mylar Flips (soft plastic are (PVC-polyvinyl chloride). Coins can get damaged inserting or removing coins
- 2x2 cardboard holders, flatten down staples to prevent scratching adjacent holder.
- High degree of protection is not required, coins can be stored safely in 2x2 paper envelopes.
- Squared coin tubes
5- Kointain, a two-piece Mylar capsule or Air-Tite holder but has a black neoprene ring.
6.- Whiteman folder offered little protection,as the obverses of coin are exposed - Albums with acetate “slides” covering front and back of the coin, can be harmful because the hard-plastic strips often scratched the coins when sliding.
Cleaner Isn’t Better
