Atari Game Questions Help!

[NESCollector75]

I recently picked up a lot of games and was wondering about the rarities of two of them.
The 1st one is called Sea Hawk and it has a picture of an airplain bombing a ship. It can be seen here: http://www.atariage.com/cart_page.html?SoftwareLabelID=2186

The 2nd is called space tunnel by puzzy and the cartridge can be seen here: http://www.atariage.com/cart_page.html?SoftwareLabelID=2075

They have undeterminded rarities so I wanted to know both the rarity and value. any help would be appriciated.
I also was wondering the value on these:
Gas Hog w/manual
Tapeworm w/manual
Nexar w/manual
planet patrol w/manual
cross force w/manual
Laser Volley (zellers label)
Dragon Treasure (zellers label)
I think the sea hawk might be a zellers lable too judging by the picture and text on it and how similar it is to Laser Volley and Dragon Treasure. Thank you!

Atari games are worth nothing. Send them to me and I will dispose of them for you.
