I came across 9 Large Cents dating from 1830-1853, but EVERY ONE has a hole drilled into it. Do they have any value or are they worthless?
The holes greatly reduce their value, but they aren't "worthless". Some people collect holed coins. If one of them happens to be a very rare variety, it could still be quite valuable.
It all depends on the overall condition of the coin and the date. Best to look them up in your Red Book.
