Oh, now I see what you're talking about. I've been tracking those, and used them to compare my coin when I was thinking about buying it (it was a helpful tool in die varieties!). Strike does seem to vary quite a bit, as one of the "XF details" coins had a very poor strike; I initially wondered how it wasn't graded VG-F!
I had been outbid on a 4R coin from one of the earlier Internet auctions, which prompted me to go on
ebay and find the coin that I ended up buying.
These Cap & Rays coins are fascinating, so many mint marks and varieties, so much history behind it. I really look forward to delving more and more into this series - I just got my feet wet, but it's an enticing swimming pool! Not to the mention the Pillars/Portraits that I'll inevitably start collecting too
