Optimal Industries has interest in sports trading card markets. In the 1980's and 1990's manufacture's of sports
trading cards over produced and flooded markets. Many of these manufacturers no longer exist. Over decades, these
cards have removed from trading markets as demand declined. As result, it's getting harder for collectors to find specific
variety of high quality raw cards for grade from this era to complete their set or to trade that produced greatest athletes of
all time. As supply of these cards continue to diminish from trading markets, the demand for these cards will rise. So, if
you are a fan of the old school, and are looking to buy high quality vintage raw cards for grade to trade or to add to
your collectors set visit Raw-Cards
