Like a lot of guys I like my cards raw. But like a lot of old guys I have to think about ease of sale and value for my heirs.

So, if you're looking for advice, here's some from a guy who didn't start submitting cards for grading until he was in his late 60's:

Have all pre-war HOFers and high demand cards graded regardless of condition.
Have all 1950's and 1960's legitimate superstars graded: J. Robinson, Paige, Aaron, Mantle, Williams, a few others.
Only submit 70's and 80's stars and rookies if you're pretty sure you'll pull at least a grade of 8.

There are lots of exceptions, I can name dozens myself, but these broad guidelines have served me well.
