Spark plug question

I got the lawnmower 9 years ago, and it has never so much as hesitated to start aside from after sitting all winter. After that, first pull start every time. Just for kicks and giggles I figured it's been 9 years so I may as well change the spark plug and this is what it looked like(R) compared to a new one(L). Is this normal for being that old? I use full synthetic oil changed before first cut of the year, and ethanol free canned gas. Front and back yard combined is roughly 4000sqft.
