1850-O Liberty Gold Double Eagle That Just Sold On Greatcollections

If the coin is truly Mint State 60 is the lowest grade possible. The marks could all be from bags or the ways it was stored over the years. If no circulation wear is present then it is not an AU coin, Gold is a soft material so possible to be scratched and scuffed without seeing circulation. That's all I got.

PS: Or else the label is wrong

Thanks for adding the picture; makes sense. This is my first post on CoinCommunity, and I'll keep this feedback in mind for future postings.

Welcome!!

First off, let's define Mint State. Solely wear/rub/friction determine whether a coin is mint state or not. A coin can have an unbelievable amount of contact marks and still remain mint state. So a coin without any degree of wear is mint state.

For Liberty Head double eagles, the main point of reference is Miss Liberty's cheek. The highest point of the design and the first that displays wear, let's observe that closely. There are a plethora of dings, bumps, and scrapes on the cheek, but the luster remains complete. Wear slightly changes the color of the metal on the high points from the oils on the skin, and that is not apparently visible here.

Next are the fields. Although there is a minor haze discoloration upon close inspection, the luster remains complete. There is no halo effect around the stars or other design elements noticed either. Below the eagle's wings on the reverse is a great place to look for broken luster as well.

The scuffing you mentioned across STATES is actually a mint made strikethrough.

Overall, I see a Mint State coin, later die state, with the dies recently polished to produce a prooflike effect. A minor mint error offers a small distraction but unique character. The detail is sharp with plenty of mint frost remaining. This coin would make a perfect addition to a registry.
