American Silver Eagle grading, in brief
American Silver Eagles (1986–present) are modern bullion and proof coins graded 1–70, but commercially only the top grades matter: MS69, MS70, PR69, and PR70. The entire value question is whether a coin is a flawless 70 versus a near-flawless 69 — and whether the grading fee is justified for a bullion coin.
It's a 69-vs-70 game — and milk spots decide it
Almost every uncirculated Silver Eagle grades MS69 or MS70. The difference is tiny: a 70 is flawless under magnification, a 69 has one or two minuscule ticks. The most common 70-killer is 'milk spots' — cloudy white blotches from the minting process that can appear even after grading. Inspect the surfaces closely under good light before paying to grade.
What graders look at
Milk spots
Cloudy white spots are the #1 reason an Eagle misses MS70 — and they can develop over time.
Contact ticks
Tiny marks on Liberty or in the fields separate MS69 from MS70.
Strike & frost
Full strike and even frost/luster support the top grade.
Proof mirrors (PR)
On proofs, hairlines and breaks in the mirror finish limit PR70.

Key dates worth grading
American Silver Eagle grading FAQ
Is it worth grading silver eagles?
Usually only for key dates, early dates with low MS70 populations, or coins you're confident are flawless 70s. Common bullion Eagles at MS69 rarely justify the fee — the certified premium is small.
What's the difference between MS69 and MS70 on a Silver Eagle?
MS70 is flawless under 5x magnification; MS69 has one or two tiny ticks or a faint imperfection. The visual difference is minimal but the value difference can be significant for some dates.
What are milk spots on a Silver Eagle?
Milk spots are cloudy white blotches caused by residue during minting. They're the most common reason an Eagle fails to grade MS70 — and they can appear even after the coin is graded.
Which Silver Eagles are valuable?
The 1996 (low mintage), the 1995-W proof, and early dates that are scarce in MS70 carry the strongest premiums when certified.
