New here and wanted to ask a question about a graded Machamp I bought a while back. Its not graded by PSA and has been marked GEM 10. Graded by All-Star Grading Co. I currently have no knowledge of this grading company and outside of PSA or BGS most seem to have no credibility. Any more information would greatly help.
Under closer inspection the card isn’t a 10 and I feel like I want to crack it out of its case if anyone has any tips on doing so that would be greatly appreciated.
