A few comparisons of value I wanted to point out regarding the value of a psa 10 grade and also I made an early comparison of the crypto #83 to the egg #213.

The only and first three brooklyn-back eggs were respectively sold for 300.00, 350.00 and 306.00. These sale prices can be verified through ebay. There havn't really been any other sales to go by as of today.
The psa 10 seems to garner a tremendous increase over an ungraded card. If you think you really have a 10 I would recommend to grade it as any crypto card will bring a higher price for that grade in my opinion.
