I am 70 and have original Elvis 45RPM records from the 50's on RCAA label value??

It depends on how many records that you have. Since they are in excellent condition and are from the 50's you could make $10,0000 or more. Whatever you do, keep them, as they are worth much now. A long time ago I had a stack of about 150 33 albums and at the time I was getting really into Elvis, but it was starting to go overboard. I made the mistake of throwing all of the records away. Don't do what I did. My feelings toward Elvis have changed since then for the better.
