Opinion On Grade And Value Of 1785 Rose Guinea Gold Coin

Probably the experts will chime in, but you can compare yours to the ones that have been slabbed here, and draw your own conclusions https://www.coinarchives.com/w/resu...&results=100

IN the link there is a PCGS VF-35 that sold for $400 and an NGC-45 that sold for 68,000 JPY (about $600), which appear to be the same type.

Perhaps these are reasonable coins to compare?

In comparison to the NGC-45 coin which is the same type as yours, I see these differences in your coin:
Obverse, the eyebrow is not evident, and the hair lines are a bit more worn.
Reverse: the scrolling that forms the edge of the shield is worn flat over 50% on your coin, but only about 10% on the NGC-45

I think yours compares a bit closer to the the other coin I mentioned. But I am also not familiar with the grading criteria that are being used. These are just my personal observations. I think you are ina better position to compare if you have the actual coin in hand.
