Coinstar Finds: Quality Vs. Quantity & Quantity Vs. Quality

The CoinStar kiosk at my local grocery store is located near the Customer Service Desk and the Self Check-Out line. I always glance at the reject bin when I walk by it -- but typically it is empty because I suppose the employees quickly take any rejected coins that a customer doesn't retrieve. But recently I had better luck.

Quality vs. Quantity: Last week I noticed that there were three small coins in that bin, and when I got closer I could tell that two of them were silver dimes. The third one was an older UK five-pence piece. Two outta three ain't bad (1st photo).

Quantity vs. Quality: Yesterday the food store employees were very busy handling the Christmas rush. I was amazed when I looked at the CoinStar reject bin -- it was overflowing with rejected coins (apparently left by a customer who probably had used the kiosk only a few minutes before I arrived)! I emptied it shamelessly and then bought the items I needed. Here is what I found:

(1) Several common US coins, and a very nice 1964 quarter (2nd photo)
(2) $6.50 in Canadian coins and 2.30 in Euros (3rd photo)

I also found small coins from six countries (including the UK, UAE, and Australia).

The silver quarter is the first one that I have acquired. I hunt for silver dimes in customer-wrapped rolls, and for silver half dollars. I think that a quarter is large enough that a savvy person will notice that it looks different than other quarters and take it out of circulation..
