You pulled a great card. Now what? If you toss it in a binder pocket or leave it on a table, you are risking damage that drops its value immediately. Proper protection takes about 10 seconds and costs almost nothing. This is the standard for any card worth protecting. Two items, both cheap, and together they keep your card safe from bending, scratches, and moisture. A penny sleeve is a thin, soft plastic sleeve. It fits snugly around the card and protects the surface from scratches. Slide the card in gently, top side first. Do not force it. These cost less than a penny each (hence the name).
