No, that is artificial toning. I would stay away from it. It doesn't look right. There are a number of red flags on this one.
Pass. I don't think it's natural either. With toning that dark, there should be a little separation between the devices and the field.
OK removed from my bookmarks. I want a rainbow toned morgan so bad, that's why I'm posting these threads
We call that "pull-away toning." If it is there, it is a strong indicator that the coin is naturally toned. However, the lack of pull-away toning is not necessarily a sign that it is AT. For example, take a look at this current thread with some gorgeous, natural Morgans. Two of them show no pull-away: https://www.cointalk.com/threads/toned-morgans-gtg.275095/
Rainbow Morgans are definitely attractive. If you are less familiar with toned coins, let me strongly suggest that you buy only TPG certified coins. You'll save yourself a lot of trouble and expense while you are learning. On ebay, 85% of the raw coins have problems - cleaning, AT, or fake (actually 85% is probably a low estimate). You don't want coins like that.
Highly questionable. But, more to the point, it's not attractive toning. Your money would be better spent elsewhere IMO.
