Gold

I made a lot of money last time I sold my unwanted gold jewelry.  I couldn't believe my eyes when I received the check.  I mean, the gold jewelry I sold were not only outdated, some are even broke.  I got more for the higher karat, less for the lower ones.  It was also the first time that I found out there's such a thing as 8 karat gold.  I thought the lowest karat was 10.  Anyway, I wonder how much money a gold bullion will sell for.  I bet a lot!!!!
