What's It Worth?

I found my old bike at my mother's house last year. I got it when I was around ten years old, so it's probably from 1970 or 1971. It's a red 442 Mustang type bicycle. I stopped using it when I was around 13, hung it in my mother's garage and it's been there since. Everything is original, tires and all, and in excellent shape, since I didn't ride it that much. I enclose a picture below.

Anybody have an idea on what it might be worth?

Thank you in advance!

Hello, I recently picked up this old Rambler because I spotted the crusty seat pan peeking at me from the back of a row of vintage cruisers and it drew me right in. I have not come across this double cog,coaster brake and top tube shifter style bike before and was looking for some information and valuation.

After a couple of years chasing it, I finally managed to get a twenties something (best guess) CCM Cleveland, that is mostly original except for the wheel set (again, best guess).

How much is this bike worth, if anyone wishes to hazard a guess.  Also, I will be offering it for sale or trade, once I get

A gentleman sent me the following note and photos -

my father purchased this bike in the early 1920's,he belonged to a bike club 
and raced for many years. i was wondering what the value is,how do i go about

rims. thank you for any information you can give me.  frank m.
