Assorted Vintage Machine-Made Glass Marbles

The image displays a collection of vintage glass marbles, predominantly machine-made, held in an open hand. The hand is holding approximately 15-20 marbles, primarily of the 'cat's eye' or 'swirl' variety, characterized by internal colored vanes or swirls encased in clear or opaque glass. The majority of the marbles in the hand exhibit a milky white opaque base with vibrant swirls of color, including shades of red, orange, yellow, brown, and blue. One notable marble in the upper left of the hand features a blue and white striped pattern, resembling a 'communist' or 'ribbon' style. Another marble shows a distinctive dark brown or black swirl. The marbles appear to be of various sizes, ranging from approximately 0.5 to 0.75 inches in diameter, consistent with standard play and shooter sizes. Observable condition issues indicate typical wear for vintage playthings, such as minor surface scratches, nicks, and flea bites, which are common from impact during play or storage. These imperfections are not severe enough to significantly detract from their aesthetic appeal for a general collection but would be noted for high-grade appraisals. No significant cracks or chips are visible. The colors remain vibrant, suggesting minimal fading. The uniformity in size and internal design for many of them points towards machine manufacturing, likely dating them from the mid-20th century to the late 20th century. No specific maker's marks or signatures are discernible, which is typical for most machine-made marbles. Their smooth, polished surfaces and consistent spherical shape indicate good quality craftsmanship for their type. The overall presentation suggests they are part of a larger collection, with more marbles visible scattered on a carpeted surface and in a white bowl in the background, showing a wider variety of colors and patterns, including clear glass and solid colored marbles.
