Terms:
Hard to Trade - These pets are worth different values to different traders. If someone wants these pets their offer will be full price, however for the most part they are generally hard to trade and as a result tend to trade for under their value. Somewhat hard to trade means you will need to go a bit under the true value ie 10-20%. Hard to trade means you will need to go quite a bit under ie 20-30% and very hard to trade means you will need to generally value them at 50% of their true value.

Things to note:
Pet prices will fluctuate according to the current month's account upgrades. For examples while Sindis are around the 10 mil region now, they were only 6-7 mil when they were a part of the Autumn Account Upgrades. Same goes for Ercuws. They were originally 8 mil but dropped to 6 mil during the Frostfire Account Upgrades.

This can go both ways, being in the account upgrades may end up raising the value of pets. For example the Dakota potions were previously selling for 4.5 mil, when the Steam Punk came along they were 5.5 mil.

Depending on the account upgrades the pet values will fluctuate and almost always be valued at 5.5-6.5 mil during their time in AU and will generally raise over time.

COSTUME VALUES
The maximum rate for costumes is currently at 15 mil.

To judge the worth of your costume, search it in trades and match the most recent price. If it is under 15 mil simply add that exact value to your pet value. If it is more than 15, it is rounded down to 15.
