Here is a link to where a complete set sold for "best offer" which means less than the asking price of $215 United States dollars..... 50 card set for $200 or less. They are not highly sought after and fall into the non sports abyss of "should be worth more but arent" . I agree they are cool looking and if you like them go after them. Cards like this I usually buy in piles at about $1 per card. A set usually would command a better premium just to have it complete. Non sports is an area where you can pick up old and fairly rare cards at bargain prices. Theres a few exceptions to this but these aint it. However, if you promote the Taj Mahal rookie card enough, who knows?
