Pretty much just what the name says. It means that the date in the die, master die or working hub has been re-engraved.
In case you are having trouble seeing exactly what Mike means I have circled the areas that show the recutting.
The term recutting is actually almost always incorrectly used. Very little engraving or recutting has ever been done on US coins. Recutting implies the use of engraving tools to go in and touch up the date by hand by cutting away metal on the die. What was really done on the date of Leadfoot's coin is repunching. In this case the date was punched into the die and then the date punch was placed back on the die and punched in a second time slightly lower. Unfortunately many people tend to use the two terms interchangably and they really shouldn't since they are the result of two totally different manufacturing processes.
