Marlin made the Glenfield firearms, not Winchester.
I found the value of a Marlin/Glenfield (similar serial) to be at about $2,700. I'm looking too, but that's the price I was able to find.
Your Glenfield model 75C will go for between 50-75 dollars on today's market.

That appears to be a Marlin serial number, dating to 1982. The Marlin Glenfield Model 25, in pristine condition, would bring $100-$125. sales@countrygunsmith.net
The Glenfield model 25 wasn't a Marlin, so determining what it actually is is not easy. Obtain a copy of Modern Gun Values and try and determine the actual manufacturer. A Glenfield version is typically worth 75% of the manufacturer's value.
$125.
about $140 depending on the condition
A Marlin Glenfield Model 60 .22 caliber semi auto rifle with a squirrel engraved in the stock and a serial number 20160178 is worth between $100 and $300. The actual value varies greatly based on its overall condition.
