Question:
I have 5 Iris pattern fruit/dessert bowls. 4 have ‘282’ stamped on bottom; 1 has ‘352’ clearly stamped on bottom and looks exactly like the others. Is this stamp a mistake making it more valuable? Thank you! ~Marcene

Answer:
The number stamped on the bottom has no influence on value. These three digit numbers are production codes or lot numbers. Your 352 bowl is from a different batch than the ones marked 282.
