If you need a new label, Clay has kindly scanned in one available here:

(this is for the 70's era games, though he has mislabeled it for the 60's)
I have opened these in photoshop to add the game's name and serial number-if you have one!

Most of the production runs for Gottlieb (but not all) seem to start at 03000, so your game would be closer to the end of the run. Agree with Darcy, the stamp was simply not centered on the zero when they stamped it. (showing the bottom of a 9 as well)
