Turnaround time hopes and dreams in Comics General Posted September 3, 2004 Just got back my moderns that were shipped to CGC on 5/18. At least another month to go for my economies shipped on the same date I'm about to send another batch of economies for grading. I hope that since it's not convention season, that I'll get them back in 3 months. Off the subject. Has anyone had a problem with the CGC slabs being curved like a banana. I spent 1 hour the other day trying to straighten one out, but to no avail.
