Many Unused 1961 1962 Pennies Showing Up In My Change!

It's my understanding that CoinStars are emptied by the armoured car companies, who would redistribute the collected coins back to the banks, or direct to the larger retailers. Coins from CoinStars are likely to get mixed in with freshly minted coins from the Mint at the armoured car company distribution centres, as those same companies are likely also contracted by the Federal Reserve to handle the fresh coinage distribution.

These companies make the most profit if they can ship coins the shortest distance possible, since more distance = more fuel = more costs. So locally sourced coins are always going to be preferred over importing fresh coinage from the Mints or surplus coinage from elsewhere in the country.
