For sale are 18 sixth plate size ( 3 1/4 inch by 2 3/4 inch ) tintype plates. The plates are hand cut from thin steel and have a deep, glossy black coat of japan twice-baked on the front of the plate and a thin coat brushed on the back as were the ones of the 19th century. Each plate comes with a protective mylar sleeve that will keep it safe until wanted for use. I have provided a scan of a tintype that was made with a plate like the ones listed above in the image section of this listing.
