Amber Carnival Glass Iridescent Round Punch Bowl Set with Bowl & 4 Cups

The Punchbowl and bases have no chips or cracks. Please take a look at the cup in the photo. All of the cups seem to have these marks at the top.

They appeared to be cracks. I don't know what caused it.

The cup in the photo is the worst one, but I'll have at least one. This punch stands 10 inches tall.
