Is there a site where u can enter the serial number on your money and see if it's worth anything??

I very much doubt it. Nor is it worth a great amount of money.

Exact year is not important, and nobody can give you the info you seek without research, which you can and should do yourself. Google the following:
Churchill Deluxe bicycle
Churchill Deluxe serial number
Hercules serial number

If the bike has a Sturmey Archer 3 speed you will find stamped on the hub the month and year it was manufactured. The bike model will generally be within a year of that date. In any case the bike is not worth a huge amount of money - well under $200.

Obviously the seller thinks the worth is $1000. It is worth whatever a buyer is willing to pay for it. You are best off looking for a website devoted to antique bikes Google Western Auto Western Flyer serial number and research the sites that come up. But it is impossible to give any kind of close estimate for a bike that is rare and not in one's immediate presence, let alone its worth to a particular buyer. If you like it and can afford it, then buy it, or make an offer you can afford if possible.

Best bet is the dealer, they can reset it. it's very complicated w/o the code. Also it may be worth getting an aftermarket radio which usually sounds better anyway.

Go to intel.com and do a search for rg8451oa. This is the model for the motherboard

This should have been emailed to you or was on the web page when you purchased it. You can email the Mfg. or look up your order number on their web site. Caution: be very careful when runiing anything that may adjust the registry.
