Era
Circa 1963 based on the listed date
Item Type
Dual autograph cuts accompanied by a certificate of authenticity
Condition
Good, showing minor paper toning and standard aging on the certificate document
Overall Assessment
This appears to be a dual signed cut piece backed by a secondary-market COA from a lesser-known authenticator. The biggest concern is the lack of reputable tier-one grading, and the sensible next step is professional resubmission to JSA or PSA/DNA
AI Estimated Value
Not an official valuation$50 to $150 raw as a generic third-party cert, whereas genuine authenticated dual cuts by Clay and Liston from this era command several thousand dollars
AI can make mistakes. This estimate is for general guidance only, not a professional appraisal. Actual value depends on authentication, condition, provenance, and market demand.
Get It Authenticated
Submit to premier tier authenticators like PSA/DNA or JSA for thorough examination, expecting standard service fees around $100-$200 per signature
