It all depends on a particular person's opinion of what they consider to be worthwhile.

So let's review...you've got 4 90% halves and 11 40% halves. Spot price is $33.40, so that's approximately $48+$54 minus face value $7.50 = $95 FRN's. Let's assume the following, to keep it simple: It took you 15 minutes to go to the bank and order halves (assuming it's local), 15 minutes to pick them up on your way home from work etc, plus a minimum 30 minutes per box to sort (I can personally do a box in 15 minutes) equals another 2 hours of your time. Of course, you still have to wash your hands afterward, plus box/bag the coin and take it to your local coin counter (you are dumping at more than one branch so as not to be noticed, right??). Don't forget to figure in cost of gas too.
That's 2.5 hours so far. Then one of the following:
-Coin counter dumps x 2 branches ($1000 each branch) @ 15 min per branch = another 30 minutes. OR
-Pre-counted bags (ex: some BofA banks will take exact-count plastic bags). Total time is 10 minutes to run your coin counter at home and pre-bag everything, plus 5 minutes per branch for 20 minutes total (assuming no waiting in line).
So that's either 3 hours total time invested or 2.75 hours invested. Let's just assume 3 hours.
Formula: (Melt - face value ) / your time invested = approx. dollars/hour. ($95 - $2 gas )/3 hours = net $31/hour. (we won't discuss taxes for purposes of this conversation)
In my book, anything more than $10 or $15 per hour is worthwhile. So to answer your question...in my opinion, yes it was worth it. I just wish I could score like this all the time.

Sometimes, I do better than this; other times, not so good.
