Storing Sportscaster Cards

I haven't found anything that can properly store these cards.  Does anyone have a good idea?  I am using shoe boxes and I stack them standing or flat depending on the size of the box. 

Sportscaster Prices Since COVID

 I haven't been able to get many Sportscaster cards since COVID, probably because these cards seem to be selling for a lot more than they did pre-COVID.

Are you noticing the same thing?

One positive - all of my work sorting the cards paid off and the cards are still sorted.
