Looks like they are both nicely restored Trojans. As for their value, you can do research on places like Gun Broker and Guns International and see what guns like that are being sold for. Remember, asking price, and selling price do not always mean the same thing. I have seen asking prices on 20ga Trojans run from $1500 - over $6000. I would never pay $6000 for a 20ga Trojan, but maybe someone else would.
The value of a gun, is in the eye of the person wanting to purchase it. A gun I might not want to pay $1000 for, another might see as a value at $4000.
As a general rule, think of 12ga Trojans as being in that $800-1500 ball park. 16g guns maybe double that, depending on condition, etc. But, there is not hard & fast rule. A gun is worth, what another is willing to pay for it.
