You need to be much more specific. 78s were made for about 50 years and 45s for about 30 years, with performances by artists ranging from Enrico Caruso to the Andrews Sisters to Elvis.
Please post a new question listing the songs and the artists, or you can use Google to search for specific price guides if you have too many to post easily.
I have a collection of New Testament 78 records. Are they worth anything or should i throw them away?
45 + 78 = 123
45% of 78= 45% * 78= 0.45 * 78= 35.1
a - 45 = -78 +45 +45 = -123 a= -123
45 * 78 = 3510
33
45-78*j
The number referred to the speed of the turntable in revolutions per minute (RPM). Vinyl records were recorded at various RPM. 33 1/3, 45, and 78
They stopped making 78 RPM records because they became outdated and technology was advancing. After the 78 RPM records of the 1900's, the 33 1/3 RPM records were created.
78 divided by 45 is 1 with remainder 33.
I heard about one that went for (I think) close to $4,000. And yes, they did release some 78 RPM's. They were for the Indian market since some of their villages didn't have electricity yet and had to rely on hand-cranked turntables.
Big Band 78's are not worth that much because they are very common, especially if they're from the 1940's. There are exceptions, of course. Picture discs and autographed copies may be worth something. Rock & Roll and R & B from the 1950's have value depending on the label. Early Rock & Roll records that are "For Radio Play Only" are HOT.
