1600's British stuff help

I was at the CAMP show in Pittsburgh last weekend and took this stuff in partial payment for a deal... the pictures do not show the luster in the devices or the nice toning. Now I know nothing about these but I went with my gut ( LOL and besides these are my profit so the downside risk is nill ) I tried to find these on the internet but there are so many varieties and mintmarks on these half crowns 






any help with grading and attribution is appreciated
thanks
Ken

I don't know if it's still listed , if not i can send a link , i was emailed about it yesterday and noticed only 125 of these sets were made which is one of the lowest ever releases , i got in just in time as hours later it was sold out.
In item details they grade the double florin as VF .
