The Awarding Legend Awards section in Gamemaster's Compendium is quite brief.
It only tells us that
An adventure should provide a payoff of one Legend Award’s worth of Treasure Legend Points per character, and should include the treasures that many creatures possess. When you are deciding what creatures you want the characters to meet, remember to note any treasure those creatures carry and include it in your total Treasure Legend Points. Creature treasure is listed in each creature’s description.
Exactly nothing in Player's/Gamemaster's Compendium tells us the correlation between Legend Points and treasure price, but 1 sp per Legend Point is a good baseline estimate.
You may consult the table of appropriate award sizes per circle at Gamemaster's Compendium, p95, to correct the LP-to-sp ratio as needed.
Liquidating the (bloody) bits is another thing altogether; the party needs to find a buyer, and even then, Haggle rolls could affect the price.
