I'm enjoying this thread almost as much as "Coins in the Fountain."
If swapping coins out of a tip jar was my greatest crime in life, I would be able to hold myself in much higher esteem.
Though I don't go to many places where there is a tip jar, many establishments have "penny cups" and "donation containers."
And, as I regularly encounter this situation, I have developed a MO.
At this point you have to decide in which camp you reside. Some folks think that knowledge is an advantage you can use for your own personal gain. (Win/Lose) I was taught that knowledge shared benefited all parties. (Win/Win) As a rising tide raises all boats.
The quick, and usually first, encounter is simply, "Hey Lady, I'll give you a buck for that dime." If I am in a hurry, and the cashier is absent, I have to decide if the coin is worth it the wait.
But as my routine is predictable, and I frequent the same establishments, I take time to get to know the cashiers. And educate them in advance. Many mornings the line is long, and the girls are busy, and I don't want to hold up the parade, so I have to wait for the day when I can take some of their valuable time.
When appropriate, I let them know that I am interested in some of the collectables that may pass through their hands, and equally willing to reward them for their efforts. Connect with the person and make a friend. My left pocket has teaching aids â€"
Wheat penny, silver dime,
War Nickel, silver certificate.
For example, when I take 10 dimes from my change jar in the truck, and insert a pre-65 dime, arrange the coins as if in a roll, and ask the cashier to pick out the odd coin, they not only correctly choose the silver dime, but have fun playing the game. If they can endure a brief explanation and history lesson, I'll give them the silver dime.
Ditto for the other examples of cashier's likely finds.
With knowledge and example in hand, the hunt is on. Success is only a matter of time.
If you think that cashier may be a greedy, self-centered person that wants to keep all the proceeds for her self, and cut you entirely out of the loop, simply make her an offer.
"I'll give you a dollar for that dime, or you can use up your lunch hour, spend $2 in gas, drive across town to the coin shop, and sell it for $1.65."
But more often than not, people want you to be the broker and gladly accept a $1 for a dime.
It gets better...
Although everyone here is a coin nut, others could care less, and the specified denomination makes it fungible.
Stop at your local rock shop and discover how many delightful stones and crystals can be purchased for less than a dollar. Put a bunch in a little leather pouch for your right pocket. Every time the ladies offer me an unusual coin, I let them pick out a twenty five cent stone.
On one hand, they may be taking advantage of me, as every one seems to have a small child at home that delights in a shiny Tiger's Eye. A reward for a wheatie. But then again...
I've been offered (by the informed,) wheaties for 2 cents, silver dimes for 50 cents, many coins for face value, and even a 1928 Red Seal $2 bill for $2.
If I only break even, I've had the opportunity to connect with lots of fun people. And maybe made a collector out of a few.

Go back and meet the meet the person. She may prove to be no one of interest. Or, a great addition to your life. What a great conversation starter.
And keep us posted.
