If it's hard to find the coins you want in the grades you want then sticking to your plan will make you happier in another less obvious way. You will of course be very happy when you finally find what you want. But the difficulty becomes the "inefficiency" that everyone scowls at. Let them scowl! "Inefficiency" mitigates the Law of diminishing marginal returns:
"A law of economics stating that as a person increases consumption of a product - while keeping consumption of other products constant - there is a decline in the marginal utility that person derives from consuming each additional unit of that product."

You can see the more extreme examples of this happening right now with collectors talking about burn-out with date collecting,
VAM collecting and die varieties. It happened to me collecting BIEs. Very easy to find on the Internet but after awhile they all started to look like the same hen with different clucks. That poor barn-yard rooster must yarn for another Sunday barbecue.
But!...the original BIE collectors had 10 very happy years of it. Because it took longer--trading with each other by snail mail. The "inefficiency" of snail mail over the Internet slowed down Econ101.
We marvel too much in this country about efficiency and speed. And yet what is it? A faster way to entropy?
