After TAG's "early adopter" soft launch in 2022, the hobby suggested we make our grading scale more intuitive-- so we listened.
In response to industry feedback, the first digit of the TAG Grade (on our 100-1000 point scale), needed to correspond to the Industry Standard Grade (on the 1-10 point scale). For example, a TAG Grade of 800-849 should be reflected as an Industry Standard Grade of 8, and a TAG 850-899 should be reflected as an 8.5.
TAG did not change its grading standards or algorithms, we merely responded to the hobby's suggestion that our three digit TAG Grade should intuitively reflect the 1-10 industry standard grading scale. In order to do this, we corrected the conversion chart which, in turn, corrected each 3 digit score assigned to the cards we had graded up to that point.
