Hi, Krystal --
I'm afraid the 1983 quarter has post-Mint damage. I'm trying to blow up the obverse image of your 1984 Lincoln cent. I don't see any signs of doubling based on the photo I see, but since you have the coin in hand you might be able to take a closer look with a magnifying glass and check. You should see prominent doubling of the ear under Lincoln's ear lobe. Here's a YouTube instructional video that should help:

Best of luck!
