  If I did the calculation right, it shouldn't be called an ingot, but rather a speck.

  Troy
  A system historically used for measuring the weight of drugs, precious metals and gemstones
  
  480 grains = 1 ounce troy
  31.1035 grams = 1 ounce troy
  12 troy ounces = 1 troy pound
  20 pennyweights (dwt) = 1 ounce troy
  1 pound = 373.242 grams
  1 pound = 5760 grains
  
  Grain
  An ancient unit which was originally based on the weight of a grain of wheat. The grain is the smallest unit of weight in the avoirdupois, troy, and apothecaries systems. Surprisingly it is identical in all three systems.
  4 grains = 1 carat
  24 grains =1 pennyweight
  480 grains = 1 troy ounce
  5760 grains = 1 troy pound
  437.5 grains = 1 ounce avoirdupois
  7000 grains = 1 pound avoirdupois
  1 grain = 0.0648 grams (0.06479891)
  15.432 grains = 1 gram
  
  If you bought a 15 grain ingot for $11.00 you paid about $10.60 over the silver value...

  Are you certain it was grains and not grams? I ask because 15 grains is 1/32 of a troy ounce and silver is currently about $13.25 a troy ounce. Therefore, you paid a rate of approximately $352 per ounce for the silver.

  15 grains is just a tad less then 1 gram, there are 31.1 grams in a troy ounce. If it is really 15 grains you paid a very steep price for that silver.

  Your math is impeccable.

  American Royal Mint sells a boat load of 15 grain "1-ounce" silver products with zodiac signs and such - they're referred to as "art bars" . They are usually a copper/brass core with minute amounts of what they describe as "Silver Coating".
  
  A typical one troy ounce silver round is 480 grains. With today's close of $13.25, the silver value in your piece is about 41 cents.
  
  The good news is almost all of these do sell around $10 for some reason, but the value is not in the silver.
