I'm not sure there is any scamming going on - there just seem to be a lot of 'clever' descriptions - describing himself as an experienced collector and then trying to pass off repro sabers and yak face baggies isn't what you'd expect
I've found recently that certain elements believe the phrase "Mint on Mint Card" seems to be some sort of caveat for sellers not to state that its a reseal...
In so far as, "well I never stated it was factory sealed"...etc
