My birthday was a couple weeks ago. To celebrate, I took part of a Friday off and went to the mountains to play poker. It was a beautiful day. And when I say beautiful, I'm talking Rocky Mountain beautiful. Believe me -- that's saying something. The drive alone made my day.

But I should've done something else. And not just because I got creamed at the poker table, either. (Don't ask. I played average, at best, and took some tough beats.) The real lowlight would come later that night in a chance encounter.

Could you spare a quarter for a house?
As I strolled out of the card room after midnight -- oh, how I wish I'd left early -- a woman I'd say was in her late 30s or early 40s asked me for a quarter. She'd had more than a little to drink and explained to me that she needed it to play a machine. Her goal, it seems, was to win a house.

That's right, I really said a house. Sounds like something that could make you go broke slowly and painfully, doesn't it?

I didn't have a quarter and so moved on, but that didn't stop this woman in her quest. I watched her accost several more people on their way out of the casino. I'm not sure how much she collected, and I never did see her go back inside to yank on her one-armed bandit of choice. Still, the scene struck me as remarkably sad.

Invest your quarters
I now realize that my dismay comes from experiencing firsthand the desperation that oozes from someone who is in constant quest of the "big score" that will change their lives. But I also find myself in awe of how little respect this poor soul had for the almighty quarter.

Seriously. Have you ever figured out what you'd have after 20 years if you saved just one quarter a day? I have. Check out the table below. The totals assume you'd be earning 8% a year in a simple index fund such as the Vanguard Total Market (FUND:VTSMX).

Year Ending Total
1 $98.55
2 $204.98
3 $319.93
4 $444.08
5 $578.15
6 $772.96
7 $879.34
8 $1,048.24
9 $1,230.65
10 $1,427.65
11 $1,640.41
12 $1,870.20
13 $2,118.36
14 $2,386.38
15 $2,675.84
16 $2,988.46
17 $3,326.08
18 $3,690.72
19 $4,084.53
20 $4,509.84


That's right; just a quarter a day invested in giants like General Electric (NYSE:GE), Kellogg (NYSE:K), Caterpillar (NYSE:CAT), Home Depot (NYSE:HD), and Microsoft (NASDAQ:MSFT) nets you more than $4,500 after 20 years. Not bad, eh? Well, it gets even more interesting were you to not invest another quarter for the next 10 or 20 years. In that scenario, your 8% annual return would bring you $9,736.41 in a decade, and would more than double to $21,020.16 after 20 years. Still interested in the one-armed bandit?

Look, I realize the apparent hypocrisy of this column. I mean, really, what the heck am I doing preaching to you about saving your quarters when I'm off blowing moolah on poker? I can get away with it because I only gamble with money I can afford to lose, and poker is part of my entertainment money. That's not to say I don't try and win; I just don't ever assume I'll pay for anything -- especially a home or our retirement -- through gambling.
