Koi Fish Slag Glass Figurine Planter / Vase

Era / Decade

1960s-1970s

Material

Slag Glass (Caramel/Chocolate marbling with opaque white glass); heavy pressed glass construction.

Condition

Good to Very Good. Shows some visible surface wear/matte texture which is common in older slag glass. No major chips or cracks are visible in the photo, but the 'teeth' on the mouth are prone to flea bites.

Demand Level

Moderate. Slag glass has a dedicated collector base, particularly in variations of caramel and 'chocolate' glass.

Resale Value

Estimated Resale Value

$25.00 - $45.00

Estimated Retail Value

$40.00 - $60.00 (adjusted for modern inflation/comparable boutique pricing)

Comparable Sales

Similar slag glass fish figurines by Imperial or Westmoreland typically sell between $28 and $55 on eBay and Etsy depending on the vibrancy of the color marbling.

Description

Vintage mid-century caramel slag glass koi fish or 'dolphin' style planter. This sculptural piece features intricate scale textures, a curled tail handle, and a sawtooth rim mouth. The marbling of the chocolate brown and creamy white glass makes each piece unique. Measures approximately 5-6 inches in height.

Key Features

Highly collectible slag glass material; popular 'fish' motif; mid-century aesthetic; unique marbling patterns; functional as a air plant holder or pencil cup.

Authenticity Indicators

Weight (genuine slag glass is very heavy); lack of visible mold seams (high-quality pressing); distinctive color swirls. Confidence: High.

Flaws to Note

Possible 'flea bites' (tiny chips) along the jagged top rim; some hard water deposits or mineral buildup likely if it was used as a real planter; potential dullness of finish from age.

Selling Guide

Where to Sell

Etsy (best for vintage decor), eBay (best for global glass collectors), or a curated Vintage booth.

Selling Tips

Use keywords like 'Slag Glass,' 'Caramel Slag,' 'Koi Fish,' and 'Mid Century Decor.' Photograph with light behind it to show the marbling and translucency. Clean with mild soap and water only; do not use abrasive chemicals.
