2 Dunlop Metal Finger Picks for Guitar or Banjo Silvertone .018 inch Wearable

Hello, you're looking at two Dunlop wearable guitar picks. They are the .018 size and metal,  but I'm unsure of the metal type used. Condition-wise they have some patina, scuffing and wear to them. And one side is slightly bent. Please see photos for more information on the condition.
