We have two (2) Coast to Coast Stores, Marquis Series, 10 Speed Touring bicycles. Does anyone know anything about them, or if they are worth anything? The serial numbers are HC7794946 and HC7808057.

We also have a 1970 Brioni New York, First Class, Leisurecraft Products, LTD. If you have any info on this bike it would be greatly appreciated.

I've spent a couple of days trying to find something on these bikes.

Thanking you in advance.
