[QUOTE="BadThad, post: 1790732, member: 17261"]San Fran was still working on some problems they had starting in 1920 with quality. All of the coins they produced through the 20's are known for their awful strikes and bad planchets. Things started improving in 1928 - as I recall the S mint workers where threatened by management- so they were still working on things in 1930. This coin had a partially filled reverse die. Grease and other particulate matter accumulates in the die recesses and prevents it from full striking-up the coin. It happens to ALL US coinage. As soon as it's spotted a mint worker changes out or cleans the die. This coin shows obvious signs of the problem. Typically, filled die coins do not effect the grade until you get to MS-65/66 and up. Back to y our question..... No, this is not a specific characteristic for the issue. The filling/clogging of dies is a random occurrence. There are plenty of well-struck 30S's in the marketplace.[/QUOTE]
