After moving to a big city, I too resolved to simplify the carry-arounds and switched from a full sized wallet to a small front-pocket model with money clip. It holds 6 cards (two credit cards plus ID’s and health card), plus the folding money.
Coins are the enemy. Unless you need them for vending machines or parking meters, leave them home. period. Spend using cards when possible. From cash transactions, dump out any acquired coins daily into a small jar. To avoid them piling up, take them to the CoinStar machine at the grocery weekly or monthly–as Dr Helen has previously pointed out, there is no fee for this if you take the money as an Amazon gift card instead of cash.
If you take trips to countries where coins are simply unavoidable (most european ones, for instance, have coins worth $3-5 apiece, not bills), or you have to have them for meters or vending, then it can be worth getting a small coin pouch.
