No there are more coin collectors,but it seems like more comic book collectors because of all the Batman movie,Avengers movie and Walking Dead good news we hear. In fact there are even more baseball card and Magic the Gathering collectors then comic book collectors. The average monthly comic book sells about 30,000 to 40,000 copies a month in the USA,and this is after the new DC 52 and Walking Dead brought in new readers.
I think in 5 years that digital comics will be the majority for sales, as the digital readers keep improving. IMHO
ahh, you learn something new everyday
