Hides are onw of the top sales in LOTRO and one of the easiest items to get since you will collect some from -killing such and such- animals. There are different types of hides:

Light Hides
Medium Hides
Pristine Hides
Exceptional Hides

You can sell them between 1 and 5 silver each depending on demand and if you ask a forester to boil them you can get more money (2 to 10 silver and more in some cases per stack of 50).

Remember that when boiling two raw hides make only one boiled hide, unless the forester have the complete tier in that case you can get lucky and receive 3 boiled per 2 raw during a critical recipe.
