## The Change is All Counted!

In honor of the last day of community week, I will be giving away a free DRK to Steve Nelson. My change jar contained exactly \$363.75 worth of change, and Steve’s guess was \$362.56, making him off by only \$1.19. Congratulations, Steve! I’ll be contacting you directly.

Now for some other interesting statistics:

Total number of entries: 76 (between comments and personal email)

Highest guess: \$764.19 (I wish!)

Lowest guess: \$98.00

Most scientific guess: 1 penny weighs 2.5 grams. 1 nickel weighs 5.0 grams. 1 dime weighs 2.268 grams. so 1 penny + 1 nickel + 1 dime weighs 9.768 grams and is worth of \$0.16. 1. assume the collection is random, but no Quarter; 2. assume the jar itself weighs 2 pounds (just a wild guess … if this is not close enough, the guess won’t). 35.5 – 2 = 33.5 pounds = 33.5 * 453.6 = 15195.6 grams. 15195.6/9.768 * 0.16 = \$ 248.90

Runner up for most scientific guess: Other than myself, 63 guesses placed. Lowest 113.08, highest 764.19…Most guesses are placed between the 300 and 400 (21 of them). Average value is \$334.60. Now, if we sample the coin count from the well lit part of the picture we assume that 35% pennies, 26% nickels, 22%dimes and 17% quarters jar contains. Distributing the total weight to coin types and calculating the actual values with per coin type unique wieght gives us \$360.00. I will go with the average of these 2 values, so my guess is \$347.30.

Least scientific guess: \$123.45

Most important lesson learned: Next time, just use Coinstar! (As Sam warned.)

Thanks for playing, all! It was fun (except the counting part)!

Woohoo! Least scientific! What do I win? ðŸ˜€

2. Do I get “runner up for least scientific guess” ?At \$345.67 I was pretty darn close ;0)

Close to \$400 in a coin jar? Dude, keep adding to it, and then bring it to MAX for beer money. ðŸ™‚

4. Would you still do CoinStar if the change was pre-sorted? 8% seems a bit steep on coins such as pre-sorted quarters…I have an abundance of sorted change which I’ve been saving for about 8 years.. recently did the CoinStar thing with the pennies since there was no way I was going to wrap and sort them myself and it came out to \$32.35 IIRC.Although, it’s nice to have the quarters around for the self-service car wash.

woah there – \$400 for beer? in NOLA? it’s only 4 days, Ben — \$200 will more than get you drunk in this town! \$400 and you’d be in a coma! ðŸ˜‰
