Group knives by tang stamp era, pattern, handle type, box or papers, and obvious damage before looking up prices.
Old Case Knives Value Guide for Estates and Inherited Collections
The safest first move is documentation, not polishing or quick pricing. Old Case knives range from common working knives to collectible examples, and value changes quickly when stamp, pattern, condition, and originality are not matched correctly.
Estate sorting workflow
Photograph evidence
Capture both tang stamps, blade profiles, springs, shield, handle cracks, pitting, and box labels in natural light.
Avoid cleaning
Do not buff, sand, force stuck blades, or polish away patina before a collector can judge originality.
Compare like with like
A boxed trapper, cleaned user stockman, and cracked Tested XX knife need different comparable sets.
Condition details that move value
Record blade loss, weak snap, wobble, cracks, rust, pitting, missing shields, replaced blades, and whether the box or papers are original to that knife. A clean user can still sell well, but hidden defects create returns and low offers.
Trapper
Case trapper knives are the broadest comparison set, so value depends heavily on era, handle material, blade loss, and whether the knife is a standard 54, mini 07, or slimline 048 variant.
6254 SS / 6254 CV / 5254
Stockman
Stockman values are best estimated by matching the exact frame number because a small 33, medium 18 or 47, and large 75 trade in different buyer pools.
6347 / 6318 / 6375
Peanut
The Case peanut is a small pattern where condition and cover material matter more than size; estate examples often need careful blade-loss grading.
6220 SS / 6220 CV / 5220
Canoe
Canoe values hinge on whether the knife is the common 131 frame or a larger gunboat-style variant, then on era, handles, and blade rub.
62131 SS / 62131 CV / 52131
Cheetah
The Cheetah is a higher-variance Case pattern because swing guards, lockup, vintage bone, and limited runs can move prices quickly.
6111 1/2L / 6111-1/2L / 5111 1/2L
Congress
Case congress knives need pattern-specific comps because small 68s, standard 052s, and large 88s do not share the same value ceiling.

Common overpricing mistakes
Treating every inherited CASE XX knife as scarceUsing active asking prices as valueIgnoring blade loss because handles look cleanCleaning before documenting originalityPricing a full estate lot from the best knife
Broad guide ranges are only starting points. A cleaned knife with heavy blade loss may fall below the range, while a boxed scarce pattern deserves a narrower collector comparison.
When to get a professional appraisal
- Pre-1940 Tested XX stamp with strong blades
- Pearl, early stag, desirable bone, or rare covers
- Factory display material, papers, receipts, or provenance
- Scarce patterns such as Cheetah, Muskrat, older Congress, or rare variations
- Conflicting stamp and pattern clues that suggest repair, reblade, or counterfeit risk
Use a qualified knife dealer, auction specialist, or certified appraiser when insurance, probate, donation, or high-dollar sale decisions depend on the number.
Check current market evidence
Compare similar sold or completed listings after identifying the likely pattern and condition. Skip bulk lots, parts knives, empty boxes, and listings that do not show the tang stamp.

FAQ
Should I clean old Case knives before selling?
Usually no. Cleaning, buffing, sanding, or heavy polishing can reduce collector value and hide evidence buyers need.
Are old Case knives always valuable?
No. Pattern, era, condition, originality, handle material, and buyer demand matter more than age alone.
What is the fastest way to estimate an estate Case knife?
Record the tang stamp, parse the pattern code, grade condition honestly, then compare similar sold examples.
