I collect certain kinds of quarters. It started out as a collection of specifically just the W mint mark ones released in (year), but eventually became a collection of the final four decades of the 1900s, and this is a stat tracker how how many I found in each $10 roll of quarters. Stats will be taken only of “dingy” rolls, as some rolls I get from my bank withdrawals are “shiny” and contain strictly same-year quarters which appear to be uncirculated aside from to myself.
