AI Appraisal Estimate

This is a vintage miniature glass bottle of Calvert Extra Blended Whiskey, commonly referred to as a 'nip' or 50ml size. The bottle is constructed from clear glass with a rounded shoulder and a long, tapered neck. It features its original metallic gold-colored screw-cap, which remains sealed with a pinkish-red paper tax stamp or security seal across the top, indicating it has never been opened. The amber-colored liquid inside appears to have a slight 'ullage' or evaporation gap, which is common for aged miniatures. The front label is primarily a deep maroon or burgundy color with 'CALVERT EXTRA' printed in bold gold lettering. Below the brand name, the label depicts two glasses—a highball and a rocks glass—suggesting serving methods. The bottle appears to be from the mid-to-late 20th century, likely the 1970s or 1980s. The condition of the label is generally good with some light scuffing and minor edge wear consistent with age and storage. The glass itself is free of visible cracks or chips, and the tax stamp shows some minor fraying but remains largely intact. This item represents a standard piece of liquor memorabilia and advertising history from the Calvert Distilling Co.

Based on my visual examination of this Calvert Extra Blended Whiskey miniature, I find it to be a well-preserved example of mid-to-late 20th-century spirits marketing. The presence of the intact pinkish-red paper tax stamp (Series 112 or similar) and the distinctive 'Soft Whiskey' branding suggests a production date between the late 1960s and early 1980s. The bottle remains sealed, although the visible ullage indicates moderate evaporation common with age-related seal degradation. The market for vintage miniature bottles (nips) is highly specialized. Calvert Extra was a mass-produced, high-volume blend, which limits its rarity. While it holds nostalgic value for collectors of distillery memorabilia, it does not command the high premiums associated with vintage single malts or pre-prohibition bourbon. Current auction data and marketplace listings for standard blended whiskey miniatures from this era consistently fall within the $10 to $25 range. The primary value drivers here are the intact label and the unopened tax stamp. There are significant limitations to this appraisal. Without physical inspection, I cannot verify the integrity of the glass for micro-fractures or the smell of the liquid, which could indicate spoilage or leakage. To fully authenticate this item, an in-person examination would be required to analyze the adhesive on the tax stamp, the glass mold marks, and the specific volume markings. For high-value spirits—though not typically required for this category—carbon dating or liquid chromatography would be the only scientific ways to verify the age and contents of the liquid. The item is appraised as a collectible only and is not intended for consumption.
