If you're using Sal's tip with just a couple books your phone might be too close. I get the best results with my iPhone 14 by zooming in 3x and having the camera farther away.
The nice, no problem Classic Head large cents have gotten so expensive that $100 is not beyond a possibility, but that would be full retail. The Grey Sheet says an AG-3 is worth $70. That’s for one with zero problems, but lots of wear. That still seems high to me. The range is more like $25 to $50 for this one.
My photography obviously needs work but the last set of pictures clearly showed that there was a lot more detail than ag or G. If detailed coins are priced at one half or one third of straight grade price than $25 to $50 seems way too low. When I looked up completed sales of similar coins on e-bay they were in the $200 range.
Most advanced large cent collectors who are willing to pay a few hundred dollars for one coin, would rather have a straight graded coin which is nice for the grade instead of a problem, ground salvage piece. This is especially true for a common date, like the 1812.
I am sure you are correct about that but folks that are trying to buy a typeset coin that has decent detail might want a coin like this. I ended up selling the coin to someone like this.
