Hi Kyle,

Thank you for contacting Mearto with your appraisal inquiry.
You might find it interesting to look at what some of these cards - in varying condition grades - have brought at one of the largest and most reputable auction houses (https://www.ha.com/c/search-results.zx?N=0+790+231&Ntk=SI_Titles-Desc&Nty=1&Ntt=mickey+mantle+1959+topps+all+star&ic4=KeywordSearch-A-K-071316).
From the photos, the condition of your card doesn't look very good but if its in better condition than it looks in the photos, it may be worth paying to have it graded and registered with one of the grading platforms.
Based on the photos and information provided, and subject to examination, this is:

A vintage 1959 Topps #564 Mickey Mantle baseball card
All Star Yankees for Bazooka gum
CONDITION: in ungraded condition but appears slightly faded and in a (cracked) plastic case.
$50-75*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, and thank you again for using Mearto.
