Tell me about this toning on two Liberty Seated dimes

Monstavet

I am basically a novice when it comes to assessing toning on older silver coins, can anyone tell me anything about the toning I see on these two coins I found on Yahoo. They are not uncirculated pieces, nor are they particularly rare dates/mintmarks, so I don't think anyone would go to the trouble to artificially tone them...are these just run-of-the-mill-normal-toning-for 100+-year-old-coins? Just trying to learn Thanks!
