a poster here visited Hong Kong and reported 30% growth/month. I thought this was abnormally high but he was there and said he got that report first hand. The company reported 30% growth/yr. Seems right to me. Maybe even a little lower than I would have thought as they are starting from such a low base.
Historically, Vintage coins grow about 8%/yr and Modern coins fluctuate wildly. So 30% international growth can help smooth all these numbers out.
It seems both Hong Kong and France send their coins to US for grading (or US graders fly out to there) but Shanghai has staffed the office for onsite grading.
