Headed back to the World in a few weeks and we wanted to do something new, so thought pressed pennies would be fun for the kids (and us big-kids too!) I have gone online to research and gotten completely overwhelmed and excited about it! So... what are some practical tips you'd suggest when starting a collection? My thoughts are to purchase ONE pressed penny book for this trip... maybe collect one penny from each country in World Showcase, plus pennies from our favorite WDW spots??? What parameters do you use because there is absolutely no way to get them all and I don't want to have to be stopping at every single machine we pass by! Also, are there some pennies that are "better" to collect than others?
