This is good advice, and it's the same advice that I was given more than 40 years ago when I started collecting ancient coins. Upgrading usually means throwing away most of what you originally spent, even years later. As a young collector, once I learned this, I would sometimes buy only 2-3 coins a year, but I not only appreciated the treasures in my very small collection more, I regretted the "bargains". Most of the bargains are gone now, but the person who sold me my first ancient coin was also the one who gave me the advice echoed by Bing. I still own that first ancient coin. Not a pristine gem but it wasn't a bargain at $65 in 1978, and I've cherished it ever since: Roman Republican Silver Denarius produced by the moneyer L. Scribonius Libo Struck Circa 62 B.C.
