Read this thread you posted in earlier. There are multiple inconsistencies with the stamp.
The card being encased by Beckett means nothing. Beckett in general is more lax about grading. Which is why people turn to them for square cuts, matchprints, fpos, etc. because PSA does not grade any of these items. On the other end Beckett also graded pack fresh charizard gx cards as “inked”. Surprisingly minimum wage employees with a few months of training don’t always get it right.
