When Morgan Toning Becomes Something More

At what point does Morgan silver dollar toning make a coin, or set of coins, more interesting than just a normal silver dollar(s)?
Below is a nice, original uncirculated roll. It has a few toners to varying degrees. What do you think of these? Do you have interesting ones of your own?
A few of the individual toned coins from the mentioned roll:
Coin #1
Coin #2
Coin #3

More interesting or more desirable? You need to have the "money colors" (vibrant orange, magenta, green, blue) to start ratcheting up the desirability, and they have to cover a good part of one side of the coin. Obverse better than reverse. Textile pattern a bonus.

@messydesk probably a decent grade doesn't hurt in addition to date rarity.

I like coin #1.
Nice roll. Agree with John, you need those vibrant colors for toning to increase value & desirability. But for any Morgan roll, having that uncirculated, no-doubt about it frost & luster, better average grade level (say avg. 63/64) and for roll purists, coins from similar dies will increase marketability. Similar VAM markings increases likelihood came from a Mint bag and not put together. Only have 1 Morgan roll but lucked out since I'm only the 2nd owner in the last 50 years. I keep the nice toned 1 separate in plastic for protection.
