Interesting. I see what you mean about the doubling on the letters of ONE CENT, especially at the top of the N's and the lower left serifs of the E in ONE, and the T. Date placement looks like N-1. Grellman does not mention this doubling on any listed variety. This could either indicate that it is a new variety, or that it is master die doubling (from repunching when the master die was made. At that time they weren't using master hubs yet and the master die was made by hand with the letters punched in.) and is then therefor present on all of the varieties.
Ok, I've looked at a couple of good pictures of a couple different varieties of 1852 cent and they also show the same doubling, so it is probably master die doubling and is on all 1852 cents.
