$20-$120
Risk depends on cracks, lever pressure, nib condition, and whether the sac has hardened.
Serviced vintage writer
$80-$300
A clean working fill system and usable nib move many common models into stronger range.
Collector-grade vintage
$300-$1,000+
Rare colors, overlays, flexible nibs, large size, and documented condition create premiums.
These ranges are educational screening ranges, not certified appraisals, insurance values, or offers to buy. Verify condition, working status, and exact model matches before pricing publicly.

Lever, vacumatic, snorkel, and piston systems carry different repair assumptions. Buyers discount unknown filling systems because parts and labor can exceed the spread.
Hard rubber oxidation, celluloid shrinkage, ambering, cracks, and plating loss can push a desirable model into restoration pricing.
