Clear wrappers are brinks wrappers. Clear wrappers can either be your best friend or worst enemy.
It depends on the person, but I personally, and many others on the forum haven't found a single dime in Brinks boxes. However, others that is all they search.
Clear wrapped coins of any sort can lead you to not check "dirty" rims. Yes, often these are clad, but often a dirty rim will be a silver, usually an older one such as a Barber or an older Merc. ALWAYS check the "dirty" rims. Unless you can clearly see a line of copper in the coin (EXCEPT in halves, you must date check those as an uncirculated 40%er will look exactly like a modern copper-nickel clad) check it! You don't want to dump a Barber!
