Libbey Rock Sharpe Old Fashioned Glass in 'Royal Oak' Pattern (Clear)
Libbey (Rock Sharpe / Safedge line) · Kitchenware & Appliances > Drinkware
Era / Decade
1940s-1950s. The pattern style is Mid-Century Modern transitioning from the EAPG (Early American Pattern Glass) aesthetic, common in Libbey's mid-century Safedge lines.
Material
Pressed Glass. Features a high-gloss finish typical of Libbey's heat-treated glass; the clarity and sharp edges of the pattern suggest a decent quality soda-lime glass, though not lead crystal.
Condition
Very Good. The glass shows excellent clarity without significant 'sick glass' cloudiness. There are no visible large chips or cracks on the rim. Minor surface scratches from storage are possible but not prominent.
Demand Level
Moderate. There is a steady market for replacement pieces in this specific pattern, though single glasses move slower than sets.
Resale Value
Estimated Resale Value
$8.00 - $15.00 (individual) / $45.00 - $65.00 (set of 6-8). Singles have much lower value than complete sets.

$4.00 - $6.00 (historical equivalent). Modern comparable quality glasses retail for approximately $8.00 - $12.00 each.
Comparable Sales
Recent eBay sold listings for single Royal Oak tumblers range from $9.00 to $14.00 plus shipping. Full sets of 4 recently sold for $35.00 to $48.00 depending on condition.
Description

Perfect for serving old fashioneds, whiskey, or water with a touch of Mid-Century elegance. Measures approximately 3.5 to 4 inches tall.
Key Features
Highly collectible 'Royal Oak' pattern; 'L' script mark likely on the bottom; heavy weighted base for quality feel; versatile for both MCM and traditional decor styles.
Authenticity Indicators
Libbey glasses of this era often feature a small cursive 'L' inside a circle or square embossed on the very center of the bottom base. Confidence level: High.
Flaws to Note
Check for 'flea bites' (tiny chips) along the faceted edges of the pattern and the inner rim. Minor shelf wear on the bottom indicates age but is expected.
Selling Guide
Where to Sell
Etsy (best for vintage kitchenware), eBay (widest reach for collectors looking for replacements), or Facebook Marketplace (if selling as a large set).
Selling Tips
Use keywords like 'MCM', 'Lowball', 'Whiskey Glass', and 'Replacement'. Photograph against a solid dark background with side-lighting to make the glass pattern 'pop'. If you have only one, list it specifically as a 'replacement piece'.
