Used and refurbished golf balls

Used golf balls are golf balls that have been played, most likely hit into a water hazard, then retrieved, cleaned up and resold. Used golf balls comes in different gradings - one well-accepted standard is:[2]

AAAAA (1st Quality)	AAAA (2nd Quality)	AAA (3rd Quality)	AA (4th Quality)
Highest quality ball in the marketplace. Like new, perfect to very near perfect. A "One Hit Wonder" Ball.	Very slightly blemished balls. May have minor imperfections.	Slightly scuffed or blemished balls that may have minor discoloration.	Appropriate for range and green practice. Survived a round of golf.

Refinished, sometimes called reconditioned or refurbished, golf balls are different than used. Refinished golf balls may look new, but do not meet the manufacturer's original requirements. In the processing procedure, the golf ball is stripped of its original surface paint and reprinted with the original markings, then a new clear/coat is applied.
