Collection vs. Accumulation
I think most of us have both. I mean we say we collect "coins", but we don't, really. We may collect Short Set Walkers, or Modern Mint Products, or a type set or a box of 20, but not everything. But I think we often buy, or at least acquire, coins that don't fit our collection, like when our next door neighbor who knows we collect returns from Canada and gives us her change, or when we buy a lot to get a coin we want, or just because it's too cheap not to buy (I had about two and a half rolls of 1973 brown Ikes), or coins we get for other reasons (my wife was asked to bring "tokens" to exchange with leaders of her company all over the country, so we purchased three rolls of New Hampshire quarters, but the company announced this very close to the meeting and she ended up only exchanging like eight quarters).
I'm not quite sure where I'm going with this, but it caused me some thought. I mean @joeykoins had his recent MS 67 "W" quarter which was clearly part of the accumulation as he got rid of it as quickly as he could. I guess that, and watching my accumulation cross the auction block, made me think of this.
