If you bought them without names, I wonder if they are seedlings. By saying "lost tag" maybe the seller thought they could get more for them.
There really is no way to know, for sure, what they are. There are so, so many daylilies that look alike. And, photos can vary the color, making it look like a different plant than it is.
Pandora's Box has 20 child plants listed in our database. A quick look shows that three of them look very close to Pandora's Box. There would probably be more, if there were photos of all the kids.

You say you want to sell them. If you do, please sell them without names.
One of the problems with guessing a name is what happens down the road, when the person who buys the plant gives it to someone else and they give to someone else... Pretty soon you have a lot of miss named plants out there. Say one of those people want to make seeds... Counting on the genetics that you guessed about.
If you had a list of names and asked us to match the flowers to the list, that **might** be possible. Without a list, and given the seller did not know the names, it would be better to leave them as "NoID"
