Sometimes it's like that. Returning them is a bad idea (if not an impossibility). You will never get another coin from that bank if you do that. I went 12/12 skunk boxes one week, then 10/10 silver boxes the very next. You need to get a thick skin if you want to have any fun at all in this hobby. Get used to rejection! If you are like most of us, you'll get a ton of skunks, but the occasional big scores will outweigh them and make the hunt worth it in the end!
Since posting on this forum your post is by far the most ridiculous one yet. No serious CRH would ever consider taking 6 boxes of unopened & unsearched half dollars back. Part of the fun is the thrill of the search & the element of surprise. If you are discouraged after getting just 6 skunk boxes, my advice to you is return those boxes & give up the hobby because you have a negative defeatist attitude but more importantly...you obviously don't have what it takes to be a CRH. Take up golfing instead...that is if you have the patience.
Even penny searchers are getting skunked for copper now. It's just a lot less common. 6 skunks would have been a big deal years ago now it's more or less the norm.
I just had my first 4 box skunk. Sucks, but I am def not discouraged enough to stop getting boxes. Gotta take the good with the bad. I try to pick up a box of pennies every time to cheer me up in case of a skunk streak.
I went through two batchs of halves with nothing, So I bought a 2 boxes of pennies. I got about 12 dollars worth of pre 1982 95% copper, about 15 wheaties, one from 1910, and the rest I set aside to put towards my new hopefully box of halves. I can get discouraged just trying to save up for buying one box of halves. So I save up till I can get 1 roll or 8 rolls. Finally out of 8 rolls from one bank, I got 3X40% halves. Its not much after gas and the face value of the coins but hey, its a start and that was a yeah! moment for me. I could have quit after driving 50 miles, using a quarter tank of gas to get 80 dollars worth of skunk halves. but I tried something else, pennies, till I found those wheaties and that cheered me enough to go back to halves. If you are going to let one setback bring you down far enough that you don't want to open coin rolls again, I would get out of the hobby. Once its no more fun, its not worth doing.
