Five commemorative coins to celebrate the centennial of the 1915
Panama-Pacific International Exposition and the opening of the Panama
Canal are the focus of legislation introduced July 19 by Rep. Nancy
The legislation, H.R. 2760, stipulates that the designs of the
2017 commemoratives should be “a close likeness” of the designs of all
five coins dated 1915 that were issued in connection with the
Panama-Pacific International Expo.
If approved by Congress and signed into law by the president, H.R.
2760 would also offer the option to make a circulating copper-nickel
clad half dollar with designs resembling the 1915 Panama-Pacific
silver half dollar.
Congress authorized the U.S. Mint to issue five different coins to
1915 in connection with the expo. The coins were struck at the San
Francisco Mint and were the first commemorative coins to bear the
motto IN GOD WE TRUST.
The 1915 coins were a silver half dollar and four gold coins in
denominations of $1, $2.50 and $50, the latter offered in round and
For the noncirculating coin program, H.R. 2760 similarly calls for
production of five coins:
➤ 75,000 each of octagonal and round gold $5 coins (having designs
resembling the 1915 program’s $50 coins).
➤ 50,000 gold $2.50 coins.
➤ 50,000 gold dollar coins.
➤ 250,000 silver half dollars.
In addition, the designs of the latter coin could also be used on
a circulating copper-nickel clad half dollar for as many as five
consecutive years, starting in 2017, if the Treasury secretary
authorizes the coins’ production and release.
If this provision were enacted, the half dollar would be produced
in two compositions, 90 percent silver and copper-nickel clad.
Production of the Kennedy half dollar could also continue, with
the circulating version of the Panama-Pacific Expo half dollar limited
to a mintage of no more than 50 percent of total production of half
dollars for circulation. (Kennedy half dollars are struck in
circulation quality, but only for collector sales, since the demand
for them is circulation is low.)
The legislation specifies that the designs of the new coins be
based on the 1915 coins, with design details written into the legislation.
Designs of the gold $5 coins would be based on Robert Aitken’s
designs used for the 1915 program’s gold $50 coins.
The gold $2.50 coin would based on the 1915 obverse design by Mint
Chief Engraver Charles Barber and reverse design by George T. Morgan,
assistant engraver at the Bureau of the Mint in 1915.
The gold dollar would be based on the obverse and reverse designs
by Charles Keck.
Designs for the silver half dollars would depict the 1915 coin’s
obverse design by Barber and reverse design by Morgan.
Surcharges would be $35 per coin for the gold $5 coins, $20 per
coin for the gold $2.50 coins, $15 per coin for the gold dollars and
$10 per coin for the silver half dollars.
The legislation stipulates the surcharges would go to the “San
Francisco Museum and Historical Society for the design and
construction of appropriate exhibitions in the San Francisco Museum
and Historical Society, including the necessary adaptive reuse of the
Old Mint, commemorating the Panama-Pacific International Exposition,
as well as the development of appropriate exhibitions at the Palace of
Fine Arts on the grounds of the former Panama-Pacific International
