OBW Roll of 1954-P. “Continental Illinois National Bank & Trust of Chicago”. Lightly Toned End Coins. OBW from: “Continental Illinois National Bank & Trust of Chicago”. 40 “BU” Uncirculated Silver Quarters. Most OBW rolls will have one end opened as a dealer had to verify the top 2 or 3 coins as BU with same date & mint mark. Some are tight on both ends, & are probably from a group where it was easy to distinguish that if one was original, the rest were too. Most likely both end coins will be somewhat toned.
