KM-411.3 $2½ 1888 Go over Mo (Briggs & Bustos auction VIII, April 2024, lot 382)
Last date struck at the Guanajuato mint in this rare denomination, the key piece with a mintage of only 110 pieces reported. Elusive as are all the 1888 issues, a very interesting fact is that all of these were struck with a reverse with a re-engraved Go/Mo mint mark, none of them show any trace of an over-assayer.
