I have just acquired a cooey model 840 western Canada limited and I have done some research and talked to a few gunsmiths and from the info i have received a top-notch "perfect" model 840 will only run up to $275.00. If i was you i would keep it. It's a great little gun.
50-100
In "Good condition" it would be worth between $20 - $25. It was made from 1963 to 1976
$649 +/- http://www.gbase.com/gear/eko-model-100-mascot-1963-sunburst
depending on the condition of your rifle,they are going for between 300-500 dollars.
The Winchester model 101 over-and-under double barrel made in 1963 is worth about $800 to about $1500 depending on its condition and features. The serial number of this gun would be helpful when determining value.
Around $150-$200 depending on its how good of shape it is in.
1963 COPPER penny is worth half a billion dollars.
$2.00
