Q: If the box of cents is from Brinks, will the dimes, (etc.) also be from Brinks?
A: Yes. There is a chance that the different denominations will be from different sources. I discovered this one small bank. Recently built about a year ago. Apparently the vault was stocked by some corporate decision-maker without understanding the current market and their clientele. They were stocked by Loomis, originally. Recently, they changed to Brinks. They still had boxes of cents from Loomis in the vault whereas the dimes were from Brinks. But the above scenario is more the exception than the rule.
