I recently added a unique and rarer Al Rosen to my Flip PC. I got very lucky and stumbled upon the auction the morning of its conclusion and thankfully took it down quite easily for $5.05 delivered to my door. My latest Rosen, for your enjoyment (but probably mostly my enjoyment):
It's a yellow Armour Coin from 1955! These coins were released in three separate years and came in packs of Armour Hot Dogs (I adore unique vintage food releases). There's a blog devoted to the Armour Coins which details all the color variations and other attributes of these oddball coins.
