Please Help Looking For Help With Half Dollar Coin Roll Hunting

When searching for valuable half dollar errors, focus on Kennedy half dollars with variations like "doubled die" errors on the obverse or reverse, "off-centered" strikes where the design is not centered on the planchet, "restruck" coins with additional strikes on top of the original design, "clipped" coins with missing edges, and specific varieties like the "heavily accented hair" on 1964 Proof Kennedy half dollars, which have more pronounced lines in Kennedy's hair; always check for mintmarks and condition for maximum value.
Key points to remember when looking for half dollar errors:
Mint Mark Variations:
Doubled Die Errors:
Look for doubled lettering or design elements on the coin, indicating the die was struck twice.
Off-Centered Errors:
If the design is significantly off-centered on the planchet, the coin could be valuable.
Repunched Date or Mint Mark:
Check if any digits or letters of the date or mint mark appear to be struck over another, creating a double impression.
Clipped Errors:
Look for coins with missing edges, indicating a portion of the planchet was not struck properly.

What I do is start here:

You will find the major varieties that the TPG's recognize; however, this is NGC, and there are some that PCGS doesn't recognize. But at the least, you can quickly know what to look for.

If I want a broad list of even more such as Doubled Dies, RPM's, Transitionals, etc., I go to: https://doubleddie.com/1801.html I also use: http://varietyvista.com/ as the layout is a bit easier.
