This is amazing small contact patch. I venture a properly inflated ball sitting under it's own official weight probably has a contact patch close to this. 2" circumference is about a 5/8" diameter (or 3/16" radius).
For Size Comparisons:
Coin......Diameter..Circumference
Quarter....0.955"......3"
Nickel.....0.835"......2.625"
Penny......0.750"......2.356"
Dime.......0.705"......2.215"
