I don't really know what you are saying? I think what you mentioned is that you have found some older proof sets in capital plastic holders and wanted to know their price. The capital plastic holder won't add much value, but it might add a little bit. None of the proof sets seam to sell for a lot until you get to 1955 or earlier. The vintage proof sets (36-42) are quite valuable.
The ones from 50-55 are decent with every year back worth more than the one before it. The half, quarter, and dime form these years start becoming collectable, but the cent and nickel still lag.
