By the 1890s, the Mint had stopped taking private commissions and moved away from producing medal series it had minted for decades, largely due to pressure from the growing number of private mints that wanted extra business. In most cases, especially for awards, the Mint kept dies in storage until needed and produced new medals as requested, proving sufficient for several years. As the 20th century progressed, these orders were discontinued and the dies were sent to the owners and/or private mints to continue striking the pieces. The last private medals produced at the Mint were struck in 1948 for Boston Schools.
