Yes, that is John Wayne's social security card.
The Social Security system may be a hot topic of debate, but if you're into little pieces of history, you can be the proud owner of John Wayne's personal social security card for the starting price of $1,000. Or own his Republican Party membership cards for $600.
There are plenty of other John Wayne's possessions up for auction over at Heritage Auctions. From what I understand, the Wayne heirs will be donating a portion of the proceeds of this auction to charity, though I cannot find an official statement to that effect on the auction site, so buyer beware.
Still, I have to admit that the thought of owning a coffee mug used by John Wayne himself for a mere $500 is quite tempting. Just stay away from the seagulls, y'all. Those are totally within my budget!
