How to Grade Coins — Free AI Pre-Grading Before You Pay Anyone
Coin grading is the difference between $40 and $400 on the same date and mint. CoinVision gives you the answer free: photograph obverse and reverse, and the AI checks luster, strike, wear, and eye appeal — so you only certify the coins that earn the fee.
The grading scale, decoded
Coins grade from P-1 to MS-70, and each step moves the price. CoinVision maps your coin onto that scale from two photos — consistently, and free.

How does coin grading work?
Graders evaluate wear on high points, remaining luster, strike quality, and eye appeal, then assign a 1–70 Sheldon scale grade. CoinVision's AI performs this analysis free from two photos.
Is coin grading worth the cost?
On key dates and uncirculated coins, yes — grade swings multiples. On common circulated coins, rarely. A free pre-grade tells you which side each coin falls on.
Can I grade coins myself?
Experienced collectors grade by eye, but consistency is the hard part — CoinVision grades every coin to the same standard, free, which beats most home estimates.
What does MS mean on coins?
Mint State — a coin that never circulated, graded 60–70. Within MS, luster and strike quality decide the number, and the number decides the price.
