BUY OR SELL?

I HAVE JUST SCRATCHED THE SURFACE OF A MOSTLY "NUMISMATIC" GOLD INVESTMENT PORTFOLIO AND AM NOT WORRIED ABOUT THE RISING PRICE OF GOLD WHICH TODAY IS AT $635.00 AN OZ. I AM NOT EVEN CONCERNED WITH THE BULLIN VALUE OF DOUBLE EAGLES, BUT FEEL THEY SHOULD BE PLACED IN A DIFFERENT ARENA OF AN AGGRESSIVE BUY AND SELL ATTITUDE. I THINK MOST OF US UNDERSTAND THAT GOLD WILL TAKE THE "ONE STEP UP, TWO STEPS BACK" CLIMB FOR A VERY LONG TIME, ESPECIALLY SINCE OTHER FOREIGN COUNTRIES ARE NOW PERSUING GOLD AS WELL AS THE "WAR INFLATION" THAT WILL CONTINUE TO AFFECT THE U.S. FOR A COUPLE OF GENERATIONS AT LEAST. THE QUESTION IS WHEN TO STOP WITH THE BULLION AND HOLD. IT TRULY IS A MATTER OF PERSONAL PREFERENCE!!! I FOR ONE WILL KEEP BUYING TO $750.00 AN OZ. DO YOU FEEL I AM CORRECT OR INCORRECT?
