if this percentage holds true to the high yield pins i will be spending $1000 by the end of today on pins from ebay. i am watching several that are high yield. one 655 grams of vintage high yield for $600 and some odd dollars. by my calculations that would produce over $2600 in todays market. if this is true i will be going full bore and reinvesting after every refine until i reach $50,000. then i will spend a little and reinvest $40-45,000 haha!
