I see that the 2 D2 coins went for £1800 - it's probably the first time that this variety has come to market in recognisable form even though they weren't catalogued as such. It will be interesting to see what they sell on for, assuming they were bought for that reason. This sale values them at around £7-900 each.
I was totally incredulous the other day when my wife declared that she was the world's number one fan of the Monkees.
But then I saw her face........................
My example definitely has polished surfaces and it might be only my imagination but all the examples of so-called F74's that I've seen appear to have the H a little further from the linear circle than your photo.
i've just noticed that yours is paired with a different Obverse as it has a Narrow Date , my example has a wide date
There may be a slight difference in width but they are both 1858 large date numerals.
Almost everyone on "The Chase" this week seemed to start every sentence with "So" - I literally exploded with anger (but they managed to so me back up again).
You're probably not aware of the wonderful Pandora's box of penny varieties that you've just opened and you'll have a fantastic time exploring and discovering these.
Enjoy the journey.
Die 3's don't come up very often so, well done. As you say, you have to grab these opportunities when you can (at least that's what I tell myself, and the wife).
