OK I just did a little research, and even though the ADPi Badge was mis-described, the person who bought it still got a deal.
The Alpha Delta Pi NATIONAL HEADQUARTERS sells a plain yellow gold Badge for $80 (White Gold for $95).
www.fratpins.com has 2 plain ones for sale: 1 is $95, and the other is $75.
The person on ebay paid $61.......so even though the description was mistaken, they still got a better deal then other places, even better than the OFFICIAL place.
So what, an inexperienced Badge collector made a mistake, it happens, not everyone is perfect.
