You can distinguish a 78 record from a 33 by their material, speed, and appearance. 78 RPM records are typically made of shellac, are thicker, and have a more brittle feel, while 33 RPM records are usually made of vinyl, thinner, and more flexible. Additionally, 78s have a larger spindle hole and grooves that are wider and more closely spaced compared to the finer grooves of a 33. Lastly, the playback speed is a key indicator, as 78s play at 78 revolutions per minute, while 33s play at 33 RPM.
