I have recently bought one for $800.00. There is one listed on gunbroker.com for "buy it now" $ 895.00. Usually looking for similar gun on www.gunbroker.com will give you an idea
Check the date code stamped on it. See related link
You would have to be more specific with details as to date of manufacture, overall condition, etc. The pre-1964 Winchester Model 70 are generally more desirable than the post-64 rifles, and that can drive the value up.
It is pre 1964 with a serial # of 496507
Mercury dimes were made from 1916 to 1945 so ALL of them are pre-1964. You can find values at many sites, such as the one linked below.
$800-$900 retail for excellent POST 1964. PRE 1964 is $200 more.
over 3 thousand
The last year before 1964 that silver dollars were minted was 1935, and they were 90% silver. The melt value at present is about $24.
300-1000 USD what if the gun is pre 1964
A pre-1964 nickel weighs 5 grams.
50-1000 USD depending on specifics.
At present, pre-1965 US quarters have a melt value of just over $5. That doesn't take into account possible collector value though. For specific values, post new questions about specific dates.
A few hundred to a few thousand depending on EXACTLY what you have and its condition.
