I like all coins, but I find that I like the size of half dollars the most. Especially when inside a slab. It just looks "right" to me. Not too big, not too small. How about you, what's your favorite denomination size?
US Coins, nickels. Canadian coins, silver 5 cent pieces. Other world coins..."larger than crown sized."
World silver crowns. I have a lot of them. I find them appealing for two reasons. First, they usually have a decent amount of silver. But second, and more important, they often have an interesting story behind the topic on the crown.
Half dimes, nickels,three cent pieces silver and nickel, silver dollars . would World Canadian large cents,silver nickels, 20 cent pcs .
I couldn't quite find the words to express myself. So I found this image which best represents my feelings about WashQuartJesse's favorite coins being halfs and dollars. edit:
