Twist Along with Cal Carter, from 1962, on Vee Jay records, LP-1041.  This is an instrumental version of popular songs of the time.  Calvin Carter, producer for Vee-Jay, is the brother of the founder of Vee Jay records, Vivian Carter, who along with husband Jimmy Bracken formed the label, named from their combined initials.  Semi-collectible, with a book value of around $100 in NM condition (although I doubt I would ever see that).  This album would be VG+.
Here is the cover or Ray Charles song, What'd I Say:

The Fabulous Johnny Cash, from 1958, is the third album by this huge country star, and his first with Columbia Records CL-1253, after leaving Sun Records. Next to At Folsom Prison, this is up there with his best recordings with Columbia.  Here is Don't Take Your Guns To Town:

From 1965, on Columbia CS-9102, comes Orange Blossom Special, the 21st record by Johnny Cash.  With the hit The Long Black Veil, as well as three Dylan covers, including Mama, You Been On My Mind, not yet released by Dylan, this album was a hit on the Pop charts as well as Country charts. Here is Mama, You Been On My Mind:

Since writing Folsom Prison Blues in 1955, Johnny Cash wanted to preform at a prison, and in 1968 finally got his wish.  Johnny Cash At Folsom Prison, Columbia CS-9639, is an essential album for anyone interested in his music.  I feel this is his best album, at least in my collection; here is Folsom Prison Blues followed by Cocaine Blues:

Following the success of the live recording at Folsom Prison, a larger plan developed for a concert at San Quentin, which was also to be televised. Recorded in early 1969 on Columbia CS-9827, Johnny Cash's 31st album went to #1 on both the country and pop charts; and spawned the hit song A Boy Named Sue.

 The final two Cash albums in my collection are both compilations. This is Johnny Cash on Harmony HS-11342 from 1969 and Understand Your Man also on Harmony KH-30916 from 1971.
Having released something in the neighbourhood of 100 records on various labels, there is a lot of Johnny Cash records out there.  In my opinion his best music is from pre 1970, until his work with Rick Rubin on the American recordings from 1994 - 2010. These are not typical Johnny Cash recordings, but great music. I don't have any... yet.

Here is an example:
