The 375 Win is the least valuable in the 94 XTR line. The 7-30 Waters is probably the most sought after. The 356 Win is certainly sought after as well. The 307 Win is a great round and has some value as well. The 444 Marlin in Black Shadow and Timber Carbine are valuable because their twist rates are correct. If in very good shape these would be going prices:

7-30 Waters: $1,300
307 Win: $1,050
356 Win: $1,200
375 Win: $875
444 Marlin STD: $1,000
444 Marlin BS and Timber Carbine: $1,250

No knock on the 375 Win, but it is somewhat anemic in ballistics when compared to the rest. Just doesn’t have the range or horsepower the others do. Then again you could cite the Gordon Gecko factor as the worth is the illusion or what it is worth to the buyer to own.
