Quick answer: MS and PF describe how a coin was made: MS (Mint State) is a regular uncirculated strike, PF (Proof) is a specially polished collector strike. The number is the grade on a 70-point scale. MS70 and PF70 are flawless at 5x magnification; MS69 has one or two tiny imperfections. The 70 premium reflects perfection and scarcity — sometimes large, sometimes not.
Decoding the label
- MS = Mint State. An uncirculated, business-strike coin (never spent).
- PF (or PR) = Proof. Struck on polished dies/planchets for collectors — mirror fields, frosted devices. “UCAM/DCAM” means ultra/deep cameo contrast.
- The number (1–70) is condition. For graded moderns you’ll mostly see 69 and 70.
MS70/PF70 vs MS69 — the real difference
- A 70 has no post-production imperfections visible at 5x magnification. Perfect.
- A 69 is nearly perfect — one or two tiny ticks or hairlines you often need magnification to find.
- To the naked eye they can look identical. The premium is for certified perfection and the smaller population at 70.
When the 70 premium is worth it
- Registry collectors — points reward the highest grade; a 70 can be necessary to compete.
- Low-population 70s — when few coins of a date grade 70, the premium reflects real scarcity and tends to hold.
- Key dates and first/early releases — perfection plus a desirable label compounds value.
When MS69 is the smarter buy
- Common moderns where 70s are abundant — you pay a lot for a difference no one can see.
- Eye appeal over the number — a gorgeous 69 can beat an average 70.
- Building breadth on a budget — 69s complete more of a set for the same money.
How to decide
- Check the population. A “Pop” report shows how many graded that high — scarcity drives the premium.
- Know your goal. Registry = chase the 70. Type set or display = a strong 69 is often plenty.
- Buy the coin, not just the number.

Frequently asked questions
What’s the difference between MS70 and PF70?
Both are flawless grades; MS70 is a regular uncirculated (Mint State) strike and PF70 is a polished Proof strike.
Is MS70 worth the extra cost over MS69?
Sometimes. For low-population dates and registry sets, yes; for common moderns where 70s are plentiful, a 69 is often the better value.
Can you see the difference between a 69 and a 70?
Usually not with the naked eye — the distinction is found under magnification.
What does “Pop” mean?
Population: how many coins of that date and grade the service has certified. Low pop at 70 supports a higher, more durable premium.
