Choosing scales for coins is not grabbing the kitchen gram-killer—you need centigram resolution and a small pan centered on the load cell. ±1 g on a troy ounce is authentication suicide when fakers micro-adjust plating.
Add periodic calibration + stable environment—cheap cells drift on low battery and even HVAC sneezes.
Serious minimum specs
- 0.01 g display resolution—don’t confuse with max capacity.
- Calibrate with M1/M2 class weight when possible.
- Wind shield for light pieces in breezy rooms.
Scale + caliper reminder
Weight without diameter/thickness is half the story—pair with PlataIndex guides on calipers and 1 oz sizing.
