What is a 2020-P Maryland: Hubble Space Telescope Innovation Dollar worth?
It's scarcer than a typical date, so even circulated examples sell above face. The best uncirculated coins are where the money is.
What would make yours worth more:
- Uncirculated condition with full original luster
- A die variety or minting error
- Certification by PCGS or NGC, which buyers expect for scarce dates
For market prices, check recent sold results for certified coins in the same grade.
Quick answers
- Is the 2020-P Maryland: Hubble Space Telescope Innovation Dollar rare?
- Yes. Only 438,700 were made, 14th lowest of the 58 regular issues in the series.
- Is the 2020-P Maryland: Hubble Space Telescope Innovation Dollar silver?
- No. It's manganese brass (88.5% copper, 6% zinc, 3.5% manganese, 2% nickel). Circulating silver dollars ended with the 1935 Peace dollar. Some Eisenhower dollars with an S mint mark were made in 40% silver for collectors, but circulation Ike dollars are copper-nickel clad.
- Where is the mint mark on a 2020 American Innovation Dollar?
- On the edge, incused with the date. On this coin the mark is P, for Philadelphia.
- How many 2020-P Maryland: Hubble Space Telescope Innovation Dollar coins were made?
- 438,700.
What to check on your 2020-P
- Make sure the mint mark really is a P. A worn or filled mark can be misread. It's what separates your coin from the 2020-D (434,454 made).
- Check the date and mint mark under magnification for tooling or added letters. Scarce dates are the ones forgers alter.
- Proof or circulation strike? A proof has mirror-like fields and frosted design details and was sold to collectors, not released in change. The 2020-S Maryland: Hubble Space Telescope Innovation Dollar Proof (108,400 made) is the one to compare with.
- Judge the grade under good light. These are sold in rolls, bags and sets, so most survive uncirculated. Value depends on luster and freedom from marks.
Low-mintage dates attract altered and counterfeit coins. Check that the mint mark and date have not been tooled or added, or buy one already certified by PCGS or NGC.
The story of the 2020-P Maryland: Hubble Space Telescope
Philadelphia made 438,700 of the Maryland: Hubble Space Telescope innovation dollar. Among the 4 designs of 2020 it was the second largest Philadelphia run, between Massachusetts: Telephone (436,750) and Connecticut: Gerber Variable Scale (440,771).
Denver struck a similar number of the same design (434,454), so neither mint's version is much harder to find.
Across the whole program it's one of the Philadelphia designs made in the smallest numbers, 5th from the bottom of 29.
More on the 2020-P
Maryland's coin arrived in Hubble's 30th anniversary year, three decades after the telescope went up aboard the space shuttle Discovery in April 1990. Philadelphia struck 438,700 of them, the second largest Philadelphia run of 2020 after Connecticut and about 4,200 more than Denver's 434,454. That small margin makes the P marginally the easier of the two Maryland coins to find.
Hubble's early years included a famous setback. Its main mirror had been ground to slightly the wrong shape; astronauts installed corrective optics on a servicing mission in 1993. The sharp images that followed made the telescope a household name, which is what the coin's starfield nods to. On a Philadelphia coin, check the solar panels, which are the largest flat raised areas of the design and pick up scuffs easily. Also look at the small stars for weakness, since a soft strike blurs them together. A clean 2020-P is worth face value or a small premium.
Elsewhere in US coinage in 2020
West Point again struck quarters with a W mint mark for circulation, this time on all five 2020 designs.
How to recognize it
The Maryland: Hubble Space Telescope design
The Hubble Space Telescope, launched in 1990, appears on Maryland's coin because the state plays a central role in its operation. NASA's Goddard Space Flight Center in Greenbelt manages the telescope, while the Space Telescope Science Institute in Baltimore runs its science program. The reverse shows Hubble orbiting Earth against a field of stars, with the inscription THE HUBBLE SPACE TELESCOPE. Joseph Menna both designed and sculpted it. Hubble's observations have refined estimates of the age and expansion rate of the universe.
The American Innovation Dollar design
The obverse shows the Statue of Liberty in profile with IN GOD WE TRUST and $1. Each reverse honors an innovation or innovator from one state or territory, issued in the order the states joined the Union. The date, mint mark and E PLURIBUS UNUM are lettered on the edge, which is where to look for the mint mark.
