SECTION 1. SHORT TITLE. 
This Act may be cited as the ‘‘National Park Service 
100th Anniversary Commemorative Coin Act’’. 
SEC. 2. FINDINGS. 
The Congress finds the following: 
(1) In 1916, Congress established the National 
Park Service as a bureau within the Department of 
the Interior to administer America’s great national 
parks and monuments as a unified National Park 
System. 
(2) From 1916 to the present, the National 
Park System has grown from 37 park units with 
6,000,000 acres of land in the western United 
States to more than 395 units with 84,000,000 
acres of land in nearly all States and territories. 
(3) The responsibilities of the National Park 
Service have grown to include— 
(A) managing national historic trails and 
national scenic trails; 
(B) administering wild and scenic rivers; 
(C) recognizing America’s most significant 
historic resources through the National Register 
of Historic Places and the National Historic 
Landmark program; 
(D) providing historic preservation grants; 
and
(E) assisting communities in meeting their 
preservation, 
conservation, 
and 
recreation 
needs. 
(4) The National Park Service Organic Act of 
1916, which established the National Park Service, 
remains the preeminent law guiding the manage-
ment of parks and articulating the Service’s core 
mission, ‘‘to conserve the scenery and the natural 
and historic objects and the wild life therein and to 
provide for the enjoyment of the same in such man-
ner and by such means as will leave them 
unimpaired for the enjoyment of future genera-
tions’’. 
(5) The 100th anniversary of the National Park 
Service in 2016 will be an occasion to celebrate a 
century of American vision and achievement in iden-
tifying and preserving our Nation’s special places for 
the benefit of everyone and the culmination of 100 
years of accomplishment by the National Park Serv-
ice’s employees, partners, and volunteers. It will also 
mark the beginning of the organization’s second cen-
tury of service to the American people as environ-
mental leaders and vigilant stewards of the Nation’s 
treasured places and stories.
(6) Coins commemorating the 100th anniver-
sary of the National Park Service will bring national 
and international attention to the National Park 
System and to the legacy Congress left in 1916 
when it established a Federal agency to ensure the 
protection of our Nation’s most treasured natural 
and cultural resources for all time. 
(7) The proceeds from a surcharge on the sale 
of commemorative coins will assist the financing of 
the needs of the National Park Service’s parks and 
programs, helping to ensure that our Nation’s great 
natural and cultural resources will endure for gen-
erations to come.
