When it was introduced, it was called .30 WCF (Thirty caliber Winchester Center Fire). At some point became 30-30. Value depends on condition. Around $ 300 would be somewhere in the ballpark. Marlin originally used 30-30 so they wouldn't have to put a Winchester "brand" on their rifles when manufactured in the caliber.
I don't know for sure, but I have a 30 WCF Model 94 30-30 carbine # 872605 that was puchased in 1920.
