HK-392, Brian Boru Dollar, struck by New York coin dealer Thomas L. Elder in 1910 to honor Irish-American peoples in both countries.  Only 225 struck in Aluminum, uncommonly seen today as they are typically closely held by individuals of Irish descent as well as SCD collectors.  Few ebay trades, averaging less than one a year - the last such sale I could confirm of an NGC piece was in 2019.  Choice Uncirculated, certified NGC MS-64, new to the population.  17 in the grade, 10 better (when last checked).  Relatively bright surfaces with no 'pest', spots or grease streaks. Images courtesy of NGC.
