Yeah, straight arm stuff is always good, if they have their thumbs attached and complete.....the largest sizes vehicles/playsets are gold too...the Aircraft carrier, the Terrordrome and the Space Shuttle Defiant Complex. The original Sears Cobra base is gold as well...it's made completely out of cardboard. As with anything, condition and completeness are key.
There are so many other things in the line that could be good so, as toys2cool alluded to, if you get some pics, people can help you out immensely more.
