Let's play guess the toning premium. What do you thing this brought recently at auction? And no cheating (we are also not looking at the earlier sale from several years ago although that can be discussed after the reveal). This coin has a PCGS guide value of $100. And a generic MS 63 (no toning) sells in the $85-$95 range on average per eBay.
Reverse toning very pretty, love those purples! Obverse is nothing special, even a bit of a negative. I think collectors prefer pretty toning to be on obverse, but that is just my gut feeling. I am thinking $350. Can't wait to be wrong by a factor of 5x.
I think that reverse brought on the bidding and hammer was $475. I’m waiting to see how much more wrong I am than @geekpryde . Edit to add that I think this is a fantastic coin.
I'm going to say it's worth $50-100 extra for the toning. And that's probably one reason I've never won a coin toned like that.
Incredible reverse toning! Too bad it wasn't on the obverse. I agree with @geekpryde that the obverse toning is a bit of a negative, for me, at least. I'm going to go with a sale price of $550.
People will pay silly money for pretty colors, but I think they still want it on better coins so I would only do $150 for the premium. However, you probably wouldn't be posting here unless it was ridiculous so it will probably be more like $500.
Because many people (including myself) think it looks pretty. And most people are willing to pay more for a better-looking coin.
And the winner is @ZoidMeister with his second guess. This toner brought an impressive $1,968.75 at GC! That is almost 20x the "guide" value. It previously sold for $940 in 2021 in a Legend auction. I liked this one as the colors are quite vibrant and it has the desirable greens. However, there is a small break in the toning to the left of the star, it is slabbed the wrong way (one can request reverse toners to be slabbed reverse facing forward), and the color is on the reverse (which I don't mind but that does lead to a lower value compared to obverse toners). As you can see, I bid $800 (before fees), which is a considerable amount for me (I like to be under that for most of my coins); still I was blown out of the water by the other bidders. To me it was around a $1k-$1.2k coin so I was surprised by the final result but not shocked (as I have seen some incredible results for toners, especially at GC).
A coin kept in a reasonably inert environment (such as a slab or other sealed holder) will take a long time to change, I should think.
