I see how our estimates differ. I'm assuming $550 for a Rydale. Also if you sell on ebay to clear $50 profit you'd need to sell and ship for $190. I'd be happy to get that it I see auctions going for $160 to $175. So I'm assuming $30 to $35 profit per $100fv.
Do you work at a bank? I'm nervous to ask for more than 2 boxes at a time.
Yes, I work at a local credit union and was actually intrigued by a member who ordered 4k in dimes every week for over a year before he made some CRH 101 errors with my branch supervisor. I am able to order as much as I want which in the past few times has consisted of 4k halves and $400 pennies - however moving forward I will severely be limiting myself on the penny boxes since the halves yield much higher profits per box with considerably less effort and easier turn over time. Plus 16 boxes of pennies are heavy to carry and a pain to open every roll!
I would suggest trying your luck with ordering 3-4 boxes at a time and following the following guidelines.
1. Be truthful, its a hobby of yours, tellers don't care what you do with your money but if you lie to them about what you are doing its kind of like betraying their trust. The guy that was doing dimes at my branch had a $5 minimum balance as a member and said his "children enjoyed searching them for certain dates" etc. Find me even 1 child thats going to search 4k in dimes a week and be happy doing so - not likely.
2. Don't dump where you pick up, I am able to do this because I order the coin, I carry the coin, I run the coin through the machine either early morning before a shift or late in evening at end of shift, essentially all the teller involvement that you run into as a member/customer I can take care of for myself which allows me to do higher volume unimpeded by the boss man.
3. Build an honest and friendly relationship with the tellers and don't give grief if pennies are new or an order is somehow missed one week. If you receive new pennies just sell them on ebay for a premium or take them to dump somewhere else. There is always next week!
