They certainly look very pretty to me. Unless you have a decent track record with ebay (lots of positives), I don't know if you will get the money you are looking for. I personally stay away from raw coins on ebay, but when I am tempted, it's only by sellers with like 500+ positive feedbacks. Your photos are a major plus though. Good luck.
Only one way to find out for sure, list them with no reserve...and let 'er rip! If you want to stack the deck in your favor, start a seven day auction this evening that ends between 7 & 10 PM EST next Sunday. Seven days generates a lot of interest. Statistics show that on average, Sunday evenings are the time when the most number of people are on line shopping. With toned coins, since it's kind of a niche market, you want to maximize the exposure of your listing. Setting a reserve, especially one that's too high will scare away bidders. Just my opinions. I'm sure there are others on this forum who will give you different opinions. Those quality photos are a big plus.
They are nice, they have nice natural toning, and you have good pics. They are common dates, but the toning is definately a positive as far as eye appeal. The blue Morgans do well too. I would definately go for the 1885, and if the price was right I might look at the 1900 too. I wouldn't be surprised if you got in the range of $45-55 for the 1900, and $75ish for the 1885. If you get 2 or more people that really like the toning of the '85 it could go over $100. Just my opinion
They are nice. The only negative with toned Morgans is being raw. With a TPG, at least one has market acceptability with regard to the toning. Those two do look good, and I am sure you will get bidders.
