The United States Mint has wrapped up its July release schedule with the 2026 Minnesota American Innovation dollar. The coin honors the invention of mobile refrigeration, a development that changed how food, medicine and other temperature-sensitive goods travel. Its obverse carries a special Liberty Bell privy mark with the number “250,” marking the nation’s Semiquincentennial.
The Mint offered the coin at noon ET in 25-coin rolls and 100-coin bags. It is the 32nd state-specific issue in the American Innovation $1 Coin Program and the last of four designs for 2026. Rolls and bags of the first three 2026 coins (Iowa, Wisconsin and California) are no longer available from the Mint, which suggests the Minnesota coin’s limited quantities may not last long.
There is a pricing story too. The Minnesota rolls and bags cost the same as the previous two releases, but that price is well above what the Mint charged in January.

Product Limits
| Product | Limit (units) | Coins |
|---|---|---|
| Philadelphia roll | 8,400 | 210,000 |
| Denver roll | 7,350 | 183,750 |
| Philadelphia bag | 3,150 | 315,000 |
| Denver bag | 2,950 | 295,000 |
| Total | 1,003,750 |
The coin counts are my own arithmetic from the announced unit limits (rolls × 25, bags × 100). Because the Mint has not published a final mintage, treat the product limits as the cap on what it can sell in these packages, not as a reported mintage.
Ordering and Buying Process
Where to buy. The coin is sold through the U.S. Mint’s online store, in its American Innovation section.
When it went on sale. The Mint opened sales at noon ET. The announcement does not describe a closing date for the sale window, so the coins are presumably available until each product hits its limit.
Price options.
- 25-coin roll: $61.00, or about $2.44 per coin.
- 100-coin bag: $154.50, or about $1.55 per coin.
Household limit. Each household can order up to 10 units of each product option. That means up to 10 Philadelphia rolls, 10 Denver rolls, 10 Philadelphia bags and 10 Denver bags.
Pricing history. The Mint charged $36.25 per roll and $123.50 per bag for the Iowa coin in January. The Minnesota prices are unchanged from the previous two releases, but they are much higher than in January, which is a big jump for roll buyers in particular.
Availability. Rolls and bags of the Iowa, Wisconsin and California coins are gone from the Mint’s site. A follow-up product is planned: all four 2026 coins will be included in the 2026 American Innovation $1 Coin Reverse Proof Set, due this fall.
Historical Background
The American Innovation $1 Coin Program
The program began in 2018 with an introductory coin recognizing George Washington’s signing of the first U.S. patent. Since 2019, the Mint has issued four coins a year. When the series finishes in 2032, it will have honored invention and innovation from all 50 states, the District of Columbia and the five U.S. territories.
The series uses the golden-color dollar format. Unlike some earlier dollar programs, these coins were made for collectors and are not widely used in circulation.
The 2026 Minnesota Coin: Mobile Refrigeration
Refrigerated transport lets fresh food, dairy, medicine and other perishable goods travel long distances without spoiling. Historians commonly link the invention of truck-mounted refrigeration to Minnesota inventor Frederick McKinley Jones, who helped develop the Thermo King unit in the late 1930s and early 1940s. The Mint announcement I worked from does not name him, so verify that attribution against the Mint’s own release materials before publishing.
The truck on the coin is a 1940s-style delivery truck fitted with an early front-mounted unit.
The Other 2026 Coins
- Iowa: Honors Dr. Norman Borlaug and his contributions to agronomy.
- Wisconsin: Shows a stylized aerial view of the Cray-1 supercomputer.
- California: Shows a young Steve Jobs against a Northern California landscape.
- Minnesota: The mobile refrigeration truck.
The Obverse Design Team
The obverse is common to all coins in the program. Justin Kunz, of the Artistic Infusion Program, designed it, and Phebe Hemphill sculpted it. The Artistic Infusion Program brings outside artists into the Mint’s design work.
The “250” Privy Mark
Every year the obverse gear privy mark changes slightly. In 2026, it includes a Liberty Bell with “250” to mark the 250th anniversary of American independence. This detail makes the 2026 coins a distinctive year within the series.
Design Description
Obverse
The obverse shows a dramatic profile of the Statue of Liberty, with the inscriptions IN GOD WE TRUST and $1. A stylized gear on the obverse stands for industry and innovation. On the 2026 coins, the gear privy mark includes a Liberty Bell with the number 250.
Reverse
The reverse depicts a 1940s-era delivery truck with an early front-mounted refrigeration unit. Icons along the side of the truck represent the many perishable and temperature-sensitive goods that could be carried long distances thanks to the invention. The design was chosen from 14 candidates.
Inscriptions read UNITED STATES OF AMERICA, MINNESOTA and MOBILE REFRIGERATION. Beth Zaiken designed it, and Joseph V. Noorigian sculpted it.
Edge
The edge carries E PLURIBUS UNUM, the year 2026, and the mint mark P or D.
Why This Matters for Collectors
1. It completes the 2026 set. Collectors who want every 2026 issue need Minnesota to finish the year.
2. The Semiquincentennial privy. The Liberty Bell “250” makes the 2026 coins a one-year variation on the common obverse, and it links them to the nation’s 250th anniversary.
3. Limited product quantities. The four product limits together total about 1 million coins. That is not tiny, but earlier 2026 rolls and bags are already gone from the Mint.
4. Mint mark choices. Buyers can choose Philadelphia (P) or Denver (D) rolls and bags, which suits collectors who assemble sets by mint mark.
5. Higher prices. The roll price is $61, up from $36.25 in January. That changes the cost of a full-year set of rolls and shapes how much people are willing to spend.
6. Program with an end date. The series ends in 2032, so it is a finite collection with a clear goal.
7. A reverse proof set is coming. The fall reverse proof set will offer another way to get the four 2026 designs, though it is a different product.
Coin prices in the secondary market can rise or fall. Buy what you enjoy.
Quick-Reference Buying Guide
- Go to the U.S. Mint’s online store and open the American Innovation section.
- Choose your product: a 25-coin roll ($61) or a 100-coin bag ($154.50).
- Choose your mint mark: Philadelphia (P) or Denver (D).
- Stay within the household limit of 10 units per product option.
- Order soon. Sales opened at noon ET, and each product has a fixed limit: 8,400 P rolls, 7,350 D rolls, 3,150 P bags and 2,950 D bags.
- Complete your 2026 set. If you missed Iowa, Wisconsin or California rolls and bags, they are no longer sold by the Mint. Look at dealers, or wait for the fall reverse proof set.
- Store the coins properly in their original packaging or in coin holders, away from moisture and handling.
