I’m a FIRM believer in using ca$h for most daily, local, retail transactions.
I carry a few buck$ of mixed coin to use to complete those transactions.
I have no buildup of coin.
Coin machines are a ripoff, though I did, for a while, use a Bank that had a coin counter machine in the lobby where one could take the receipt to a cashier and deposit it at 100%.
When TD Bank had the coin counter machines in the lobby and didn’t charge anything for the convenience, that was great.
