Just watch out as there are some sets of Centennial "seconds" out there. Some online dealers have sold them openly but I bought a set a few years and didn't realize it until it was too late to do anything about the deal.
If you buy these check them in person before paying. Look for the stripe areas being properly centered and run your fingers over all the numbers feeling for raised areas or chips. Ideally put them on a table, put a straight edge like a level across them and check they are all close to the same size. (Centennials are supposed to be the most accurately matched sets for size that Aramith make I believe)
