Illinois. 28th Illinois Regiment. Undated (1861-1865) D.B. Smith. 50 Cents. Schenkman IL-28-50B (IL-D50B), W-IL-140-050b. Rarity-9. Brass. Plain Edge. EF Details--Damaged (NGC).
25.0 mm. Medium golden brass surfaces with ruddy fingerprints on both sides. A faint waviness in the flan seems largely due to the very thin fabric being stressed in striking, though there are some gentle bends which are to be expected for such a thin piece used in the manner intended. A bit worn through the centers, and with fine scratches on the reverse, but the name of the sutler is bold. All denominations on this issuer are very rare.
From the Bill Kelly Collection of Civil War Sutler Tokens. Collector tag with attribution notation included.

Estimate: $300
