The one with the teeth and the painting represents a mandau of the Papoea from New Guinea. This one is a tourist item from the second half of the 20th century.
The other one looks nicer but is rather recent as well as Battara said. The coin could be added any time.
Before buying enthousiasticly i strongly advise you to study on this forum and look at the differences between the real stuff and tourist items.
Don't be disapointed. We all have collected items at the attic from our beginning period.
