1 dollar Eisenhower 1776 1976 thickness? [επιλυμένο]

Hello. I have 1 dollar bicentennial 1776-1976, type 2, copper- nickel clad copper, but thickness is 2.5 mm. Here, on numista is written 2mm thickness. Error on numista or something else? Diameter is 38mm.

The dimensions of the 1976 Eisenhower Dollar are the same as all the other Eisenhower Dollars including the thickness of 2.58 mm.

​Then is mistake on numista. page. https://en.numista.com/catalogue/pieces3366.html
