The Irish coins are part of a redundant currency and have little or no value. See the related questions for the English coins.
The US did not mint any half dollars dated 1800.
Face value unless it is crisp and unfolded.

Unless it is in a mint set, if it is dated 1965 or later, it is only worth face value. If it is dated 1964 and before, it is 90% silver worth about $5 for the silver value with additional premiums depending on the year.
The dual dated Eisenhower dollars are face value only.
