It’s been a while but is that $17.50 sale back on 3/28/21 correct? There’s nothing special happening in this issue to justify such a price.
Just a MCS sale from 4 years ago:

Its a tricky one as there are other Blue Beetle #22’s and sellers do not often add the year or other distinguishing info on the sales listings. I was, however, able to find a few more recent sales to update the valuation.
