How much do you think these Lego's are worth? I've got some very old LEGO brick from the 50's, and am wondering how much they are worth. I'd like an estimate because I know that they are now collectors items that might be worth something.

Here are some of the items:


Three Lego Beatles that are in plastic very good condition in red black and grey 
A plastic red fire truck and a tanker that is red with written "Esso" on it and other small size Lego plastic trucks
The Lego set 810 with all the items inside 
Another big box of Legos that is in wood 
Box number 750 containing some architectural buildings   


Instructions are included with each box.
My answer to this kind of question is always "it's worth exactly as much as someone is willing to give you for it."

That said, one could look up prices on BrickLink (assuming there are any for sale there) and go from there. Failing that, put them on eBay with a reserve/starting bid of whatever minimum amount would make it ok for you to part with them.
