Welcome! You've come to a great place to share and learn about coins! First of all, your coin is normal. WAMs were normal on memorial cents until 1993 when they changed the design. You want to look for the WAMS on the 1994-2008 pennies. On 1992 and back you want to look for close AMs. Good luck and happy hunting!

I still have no idea why it is labeled as a Wide AM. I also believe this transitional variety has been removed from listings. In the event of die deterioration or a die polishing the crossbar and design of the G would look like a rev of 88. The 88 is the one to look for. But only look at the FG not the AM.
