DEAR DIGGER I HAD BOUGHT YOUR PATENT MEDICINE BOOK A WHILE BACK AND SOMETIME LATER FOUND A PONTILED SARSAPARILLA FROM NASHVILLE TENNESSEE. I HAD NO IDEA WHAT IT WAS WORTH ( I FIGURED $250.00 TO $300.00 DOLLARS) THEN I LOOKED IN YOUR BOOK AND SAW WHERE ONE LIKE IT SOLD FOR OVER A THOUSAND DOLLARS, WITH THIS INFO I PRICED MINE AT $1400.00 AND THAT'S WHAT I GOT. SURE WAS A GOOD INVESTMENT (YOUR BOOK THAT IS) . A GOOD PRICE GUIDE ON ANY SUBJECT IS WELL WORTH THE MONEY !! HOPE PEOPLE DON'T TRY TO HOLD ON TO $25.00 OR $30.00 AND LOSE $1100.00 WHICH IS WHAT I WOULD HAVE DONE HAD I NOT HAD YOUR BOOK. THANKS BILL PARKER
