A re-punched date usually only shows traces of the original punch, that is, areas that were not completely effaced before the second effort
Guess I'm still not understanding it. The first punch was lower than the second punch. It was re-punched higher, this leaving the 8 under the 8, showing in the top loop. Where did the bottom of the first punch go? It should also be showing below the bottom loop, just like the top shows in the middle of the upper loop? I guess this is just over my head.
Rookie with bad eyes, take what I say with a grain of salt and call an expert in the morning!
