Choosing among collectible silver pieces is less about finding one universal winner than deciding what you want to display: a familiar art reinterpretation, an architectural theme, a sculptural coin design, or a studio art bar. This coins paper money comparison separates the four by format, silver content, presentation, and listed price so that the choice fits the kind of piece you want to add.
Quick take
- Choose the 2021 $1 Oglala Lakota Sioux Native Spirit War Horse 1oz Fine Silver Coin for the lowest listed price and an ultra-high-relief War Horse design.
- Choose the 2014 - Niue -Secrets of Pena - Crystal Art collection - 2oz silver coin for a 2 oz, 0.999 silver piece centered on the Crystal Art collection and Pena theme.
- Choose the 2023 Niue Pop Art Mona Lisa 2 oz Proof Silver Coin for its proof designation, pop-art Mona Lisa treatment, digital printing, and gilded high relief.
- Choose the H ALVIN SHARPE HAS .999 Silver Studio Art 2.2 Oz EV Catoe Collection Bar when a signed studio art bar is more appealing than a coin format.
Listed price comparison
| Piece | Listed price | Price position |
|---|---|---|
| 2023 Niue Pop Art Mona Lisa 2 oz Proof Silver Coin | USD 424.99 | |
| 2014 - Niue -Secrets of Pena - Crystal Art collection - 2oz silver coin | USD 356.90 | |
| 2021 $1 Oglala Lakota Sioux Native Spirit War Horse 1oz Fine Silver Coin | USD 206.50 | |
| H ALVIN SHARPE HAS .999 Silver Studio Art 2.2 Oz EV Catoe Collection Bar | USD 824.99 |
The listed range runs from the 1 oz War Horse coin to the 2.2 oz H Alvin Sharpe bar. The two 2 oz coins sit between those endpoints, but they target notably different collecting interests: Pop Art Mona Lisa emphasizes a modernized art subject, while Secrets of Pena belongs to the Crystal Art collection.
Decision matrix
Start with format. Three choices are coins, while the H Alvin Sharpe piece is explicitly a bar. A collector building a coin-focused group will naturally narrow the field to the Mona Lisa, Secrets of Pena, and War Horse pieces.
Then choose the visual theme. The Mona Lisa coin brings a classic artwork into pop art, with digital printing and gilding. Secrets of Pena draws on the Pena palace setting. War Horse centers on a Native Spirit warrior-and-horse motif. The studio bar features the "Moses The LAW 180 GENERATIONS, OLD AND STILL VALID" theme.
Use metal content as a practical divider. War Horse is listed at 1 oz of 0.999 silver. Mona Lisa and Secrets of Pena each list 2 oz and 0.999 fineness. The H Alvin Sharpe bar lists 2.2 oz and .999 silver.
Consider presentation details last. Mona Lisa is identified as proof and includes a stated mintage of 500, while War Horse is identified as ultra high relief. Secrets of Pena has a Mint of Poland certificate. The H Alvin Sharpe bar carries a reverse signature by H Alvin Sharpe.
Product notes
2023 Niue Pop Art Mona Lisa 2 oz Proof Silver Coin
This is the choice for a collector drawn to art-inspired coins with a clearly contemporary finish. The Mona Lisa image is rendered in pop-art style, and the description calls out digital printing, gilding, and high relief; the title also identifies it as a 2 oz proof silver coin. Its 0.999 fineness and 2 oz precious-metal content make it comparable in substance to the Secrets of Pena coin, but the visual direction is entirely different. At USD 424.99, it sits above the other 2 oz coin in this group. That higher listed price is the key limitation when the collection priority is simply acquiring a 2 oz silver coin rather than this particular Mona Lisa interpretation.
2014 - Niue -Secrets of Pena - Crystal Art collection - 2oz silver coin
Pick Secrets of Pena when a Crystal Art collection piece and Pena palace subject matter suit your collection better than a pop-art portrait. Minted by the Mint of Poland, it is listed as 0.999 silver with 2 troy ounces of total precious metal content and a mint-issued certificate. Its USD 356.90 listed price places it below the Mona Lisa while retaining the same 2 oz stated content. The tradeoff is its 2014 date: shoppers specifically seeking one of the newer-dated entries here may prefer the 2021 War Horse or 2023 Mona Lisa. It also focuses on an architectural Romantic-era theme rather than the character-driven imagery of War Horse.
2021 $1 Oglala Lakota Sioux Native Spirit War Horse 1oz Fine Silver Coin
The War Horse is the clearest fit for someone who wants the lowest listed-price entry without leaving the .999 silver coin category. It is identified as a 1 oz coin with an ultra-high-relief strike, and its warrior-and-decorated-horse design gives it a more sculptural subject than the art and architecture themes elsewhere in this comparison. The item includes a Mint COA, and its USD 206.50 listed price is the group's lowest. Its limitation is metal content: at 1 oz, it has less stated silver per unit than both 2 oz coins and the 2.2 oz studio bar. Choose it for the War Horse design and relief treatment, not for the highest stated silver amount.
H ALVIN SHARPE HAS .999 Silver Studio Art 2.2 Oz EV Catoe Collection Bar
This H Alvin Sharpe piece is for a collector who specifically wants a studio art bar rather than another round coin. It lists 2.2 oz of .999 silver, making it the highest stated metal-content option among these four, and the reverse is signed by H Alvin Sharpe. The title also connects it with the EV Catoe Collection, while the design text centers on "Moses The LAW 180 GENERATIONS, OLD AND STILL VALID." At USD 824.99, it carries the highest listed price in the comparison. The important limitation is format: its bar shape will not match a collection built around coins, proof issues, or coin-specific themes.
Final recommendation by use case
For the most accessible listed-price entry, choose the 2021 $1 Oglala Lakota Sioux Native Spirit War Horse 1oz Fine Silver Coin. For a 2 oz silver coin with a palace-centered Crystal Art theme, choose 2014 - Niue -Secrets of Pena - Crystal Art collection - 2oz silver coin. For an art-forward proof piece, the 2023 Niue Pop Art Mona Lisa 2 oz Proof Silver Coin is the focused choice. For a signed .999 studio art bar with 2.2 oz stated content, choose the H ALVIN SHARPE HAS .999 Silver Studio Art 2.2 Oz EV Catoe Collection Bar.
