I found one of those Irish coins in my backyard the day I bought my MXT Pro...got a half-dollar signal and was pumped....stupid foreign worthless 'money'.
Its an Irish penny, dated 1941, its fairly common (mintage of about 4.7 million, about average for Irish pennies, although that would be scarce when talking about modern US coins!). And its bronze.
