45 rpm vinyl value

Does any of the analog collectors know if there is any value to some inherited RCA 45 rpm records I have? They are not full sized album 45's. They are the size of the old 45rpm singles. This is the first time I have ever seen classical music on such a format. They are RCA Victor WMO 1227 Chopin Favorites and WDM 1313, Beethoven Symphony No. 5. The albums are red and come without any dates. This was the day of "stack and play" and you have a frisbee in the making. I don't use 45 rpm so I haven't listened to these. Perhaps an analog historian would be best to comment on these. Jallen
