Whiskey of the 1870's?

Just got done watching the 2010 remake of True Grit for like the 8th time and I trying to hunt down a bottle or multiple bottles of whiskey from the 1870's. There has to be some still out there somewhere and I'm a collector of antique items and that would make a great item for my collection. Not a big drinker so I wouldn't know where to start looking. Any help would be appreciated. Any links, or other suggestions for my antique collection would also be appreciated.
