dont know about TOB, it may be an in house designation. the 10K is a designation of the gold content. 10 karats is considered junk. pure gold is 24 K, and is a soft metal, that requires diluting to firm it up. 18 K is considered the world standard of gold. most commercial jewerly is 14 K. less than 14 K is junk. a gold ring of 10 K would be worth about 10 cents, or you might find it in a cracker jack box. a ring of 14 K would be worth between $200 - $400. a ring of 18 K would be approx $800 - $4000. these values are for gold, not for gold plated. gold plated are simply not worth much of anything.
This means 10k gold.
