I have two wrenches that are clearly stamped with numbers on one side but if you flip them over the large one  ( which is a # 5 ) clearly shows a reverse 5, also I should note that the numbers are always reccessed but the reverse number is popping out, as if they punched the wrench so hard when pressing the number that it went all the way thru to the other side but I know that is not an option because the wrenches are way to heavy of a steel.
What might this indicate? What sort of hints to the stamping process should I be picking up here but am just not seasoned enough to be seeing.
The other wrench is clearly marked a # 1 on one side but when flipped over you can see fainly a # 2 popping up and over that # 2 in the center is a reverse one.
I know the pict. suck its not my fault

Sounds to me like they were stamped too hard or while the metal was stillhot, thus stmping through. Can't say about the 2.

Sorry, forgot to also mention that the reverse numbers in no way line up with the direction of the numbers on the front

Oh, then disregard my supposition. You got me on this one.

If the machine operator is sloppy and lets the machine stamp the letter die into the anvil with no wrench in it, it will leave a depression in the anvil. Wrenches stamped in the machine may pick up the reverse depression when the face is stamped...

You are one smart cookie Rusty, thanks again

I noticed the backwards "5" on the wrench, and thought you would enjoy it.
