MS70 stands for Mint State 70 — the highest grade a coin can receive on the 70-point grading scale used by the leading grading services. When you see MS70 on a certified holder, it means professional graders could not find a single flaw on the coin, even under magnification. But what exactly does that mean, and is a perfect grade always worth the premium? This guide explains it in plain language.
What “Mint State” Means
“Mint State” describes a coin that has never been in circulation. It has not been spent, carried in a pocket or passed from hand to hand, so it shows no wear at all. Mint State grades run from MS60 to MS70. The number tells you how close the coin is to perfect: an MS60 has no wear but may show plenty of marks from production and handling, while an MS70 is flawless.
- No wear: every Mint State coin keeps the full design detail it had when it was struck.
- Differences come from marks and quality: contact marks, hairlines, luster and strike separate one Mint State grade from the next.
- 70 is perfect: under 5x magnification, an MS70 shows no post-production imperfections whatsoever.
What Graders Look For in an MS70 Coin
Independent grading services such as PCGS and NGC examine every coin under good light and magnification. To earn MS70, a coin has to pass on every point below:
- No visible imperfections: no contact marks, scratches, nicks or hairlines under 5x magnification.
- A full strike: the design, lettering and rims are completely and sharply formed.
- Original luster: the coin keeps the natural cartwheel shine it had when it left the mint — a sign it has never been cleaned.
- Outstanding eye appeal: nothing distracts the eye, from spots to uneven toning.
Grading is part science and part trained judgment. That is why coins are usually examined by more than one grader before a final grade is assigned.
MS70 vs. PR70
MS70 is used for business-strike coins — coins made the regular way, whether for circulation or as bullion. PR70 (sometimes written PF70) is the perfect grade for Proof coins, which are made especially for collectors.
| Feature | MS70 (business strike) | PR70 (Proof) |
|---|---|---|
| How it is made | Standard production on high-speed presses | Polished dies and blanks, struck more than once |
| Typical look | Frosty, satiny luster | Mirror-like fields, often with frosted (cameo) designs |
| Made for | Circulation or bullion | Collectors |
| Highest grade | MS70 | PR70 / PF70 |
Neither one is automatically “better.” Their value depends on the specific coin, how many perfect examples exist and how much collectors want them.
What Really Drives the Value of an MS70 Coin
A perfect grade describes condition, not rarity. Two MS70 coins can be worth very different amounts. Keep these factors in mind:
- Certified population: how many coins of the same type and year have already been graded MS70. Many modern bullion coins are produced in huge numbers and sent for grading straight from the mint, so MS70 examples can be plentiful. When thousands exist, the premium is usually modest.
- Rarity of the issue: a low-mintage coin in perfect condition is far scarcer than a common coin in the same grade.
- Coin type: some series are much harder to find in top condition than others because of their design, metal or how they were handled at the mint.
- Collector demand: history, popularity and set-building all affect what collectors are willing to pay.
| How common the coin is in MS70 | Typical effect on value |
|---|---|
| Very common | Small premium over lower grades |
| Uncommon | Moderate premium |
| Rare | Strong premium |
| Extremely rare | Can be many times the value of the next grade down |
Things to Watch Out For
- Paying for the number alone: make sure the premium matches how scarce the coin really is in MS70, not just the fact that it is “perfect.”
- Uncertified claims: a seller calling a raw (ungraded) coin “MS70 quality” is giving an opinion, not a grade. Look for coins certified by a respected service.
- Budget: perfect grades can be costly. Choose coins you genuinely enjoy and that fit your collecting plans.
Where MS70 Fits on the Full Grading Scale
The 70-point scale (often called the Sheldon scale) covers coins in every condition:
- 1–58 (circulated grades): from Poor through Extremely Fine to About Uncirculated (AU50–AU58). These coins show some degree of wear.
- 60–70 (Mint State): no wear. Higher numbers mean fewer marks and better luster, strike and eye appeal.
- “Details” grades: coins that are genuine but have a problem — such as cleaning or damage — may receive a “Details” label instead of a numerical grade.
Frequently Asked Questions
What does “MS” mean on a coin?
MS means Mint State: the coin has never been in circulation and shows no wear.
Is MS70 the highest grade?
Yes. MS70 is the highest grade for business-strike coins, and PR70 is the highest grade for Proof coins.
What is SP70?
SP stands for Specimen — a special strike that falls between a business strike and a Proof. SP70 is the perfect grade for those coins.
Is an MS70 coin always a good buy?
Not automatically. Compare the price with lower grades and check how many perfect examples exist. A perfect coin is wonderful to own, but its value depends on scarcity and demand.
The Bottom Line
MS70 is the mark of a flawless coin, and that perfection is what makes these pieces so appealing. Understanding how the grade is assigned — and what truly drives value — will help you choose MS70 coins with confidence and build a collection you are proud of.
