United States Postal Service Newluck 2017 Celebration Corsage Two Ounce Forever Full Sheet of 20 Postage Stamps Scott 5200

Are these 70 or 71cent stamps?

Are these nonmachinable stamps?

I am curious to know if i can use these as international stamps? these popped up when i was searching for them, but i am not sure! it's for my wedding

Hello, Just double-checking that these are 70 cent stamps since I need them for my wedding invitations. Thanks!
