I presume nothing has changed since they started making the W quarters -
https://www.usmint.gov/news/inside-...-circulationAccording to the following from that link, this is how did the first ones - "In total, the West Point Mint will strike 10 million quarters that will be mixed into bulk bags of quarters at the Philadelphia and Denver Mints. In early April, the first of the W mint mark quarters will be shipped and distributed to banks and financial institutions by the Federal Reserve. The coins will likely begin to appear in circulation within four to six weeks and will be available throughout 2019."
