Go to the tourist sites in your area. Pressed penny machines can be found at zoos, theme parks, museums, aquariums and observation decks. The easiest way to collect pressed pennies is just by visiting popular area attractions and keeping an eye out for the distinctive rolling mill machines.
Try eBay. EBay or other online auction sites can be a good way to expand your pressed penny collection and to find those pennies that aren't easy to track down.
Check out coin shops and garage sales. Older pressed pennies are often found in coin shops and in other places like garage sales, yard sales and flea markets. Be sure to keep an eye out for pressed pennies any time you visit a place where used items or collectors' items are sold.
Visit the Penny Collector website (see Resources below for link). The Penny Collector website offers an online trading tool (for a price) and lists locations of all pressed penny machines by state. This website also gives tips on how to maintain and grow your pressed penny collection.
