1971-s

[ericoins]

I finally got around to cracking open a couple rolls of uncirculated 1971-s cents I’ve had for years and both rolls are filled with machine doubled coins. I can’t remember exactly where I got them, or why I have them. Is it common to find examples of machine doubling for this date?

Its common on any date

Klocc is right, its common on about ant date and mintmark. Even if it wasn't it would not make the worthless doubling worth anything. It's basically damage and in a true collector's eyes its not collectible.
