Something's Rotten In Denmark

I'm reading the Monday Morning Briefing on the Coin World site and they're reporting how an individual inherited two previously unreported metal content errors for a wartime issue cent that was supposed to be issued in steel. There were also two other rather rare coins included in the find. The man states his father never discussed the coins so he has "no idea how he acquired them." Seems his dad used to be a die setter at the Philadelphia Mint. Hey, I have an idea how he might have acquired them. Yeah, that's right, in his change. If the government can seize those 1933 gold double eagles wouldn't the same apply here (yeah, I know, the cents were authorized, albeit in another metal). When the mint hires workers are valuable mint errors listed as job benefits?
