To the best of my knowledge (and I was once told) The coast to coast shotguns were made by Mossberg. Master-mag is the coast to cast house name brand. The evidence I see that Mossberg was the manufacturer it the thumb slide safety.
According to: www.fountainfirearms.com/invlist/shotguns_list.htm COAST TO COAST CC660 20GA 27 BLUE SHOTGUN P $195.00
I just bought a model cc660 12 guage used for 110 USD. So somewhere around there.
around 150.00 dollars
I believe Mossberg made the Coast to Coast branded shotguns. I know they did while we owned our store.
Mossberg
It was made by Savage for Coast to Coast. It is a Savage Model 58.
You will need to provide more information than that. I have never heard of a Coast to Coast shotgun, even as a trade name. I think they are Master Mag which I have heard was an in store version of the Mossberg 500. Coast to Coast is the store it was sold at I believe. The above is correct. Coast to Coast was a Hardware store which sold various guns. Mossberg manufactured guns for coast to coast to sell. Coast to Coast relabeled these guns with their own model names. The CC 660 was the same gun as the Mossberg 600 which is now similar to the current model 500. Roughly worth 200-250. The one thing I'm not sure about is this. There are several variations of the model 500, but which variation was used to make the cc660. So again with that said, 200-250 USD.
Remington model 11
savage made this model,orig model is a 77
Savage Stevens
$250
This gun was made by Savage/Stevens as the Model 77. Made between 1955 and 1971. Value depends on condition, but it will value between $100 and $175. A Coast to Coast mod 267 is a Savage mod 77. The value will depend on condition. Have it assessed by a gunsmith.
