Thanks for the additional info. I got nine pieces of US-PI silver coins from the Auction held this afternoon by the BNSP at Tropical Hut along Scout Borrromeo Street corner Panay Avenue, Brgy. South Triangle, QC. And I brought home four Manila coins: 10c 1937-M, 20c 1937-M, 20c 1938-M and 20c 1941-M. Although they were presented as Uncirculated condition and the year marks were all readable, it seems that they are still not well struck compared with the 1945-D and 1944-D coins in my collection.
