The coin in our photograph is a special proof coin made especially for collectors. Most Irish one penny coins do not look so spiffy -- they looks like plain old copper coins. As with all modern issues made of non-precious metal, this coin is worth very little:
worn: less than $1 US dollar approximate catalog value
average circulated: less than $1
well preserved: less than $1
fully uncirculated: $1
I think the bird on the coin is a stylized peacock, but the artist overran the bounds of his or her artistic license.
