It depends on whether you want the mass of a circulated or uncirculated quarter and the accuracy and precision you desire. A good balance (found in many science laboratories) would give you the mass of an uncirculated quarter probably with all the accuracy you need. It would do the same for a circulated quarter but it would be accurate for only that quarter. To get the average for circulated quarters you could mass a roll of quarters on a good balance or spring scale (postal scale. grocery scale, etc.) and divide by the number of quarters in the roll. For highest accuracy you should remove the quarters from their container.
