HI, I'm new to the forum and wanted to ask a question about collecting graded books. I was offered to purchase a PGX 8.0 restored comic with minor (A - Amateur) restoration. It is Avengers #1 (1963). Does anyone has an idea of the value of this book? It's hard for me to figure out as it is PGX, and it is restored, and with Minor Amateur restoration. An estimate of the value would be nice to help me decide to purchase the book or not. Thanks!
