Found in the ground at a old house, the errows are on the 5 , the bottom of the 5 is flat, the 1 you can see better in this photo, on the left side of the 1 top and bottom the silver bubble out on the side, like it ran some. In photos it is sometimes hard to see errows, the 1 and 5 are not shaped like they should be, hope this helps, John S
