The 1900 O/CC Morgan Dollar with VAM 11 variety in uncirculated condition has the potential to be a very valuable collector's item. Here's a breakdown of the factors affecting its worth:

Desirable Characteristics:

• Overmintmark Error: The "O/CC" signifies an overmintmark error, where a New Orleans mintmark ("O") was mistakenly punched over a Carson City mintmark ("CC"). This error adds significant collectability for error coin enthusiasts.
• VAM 11 Variety: VAM stands for the Variety Attribution Module, a system used by numismatists to identify subtle die variations within a specific coin issue. VAM 11 is a recognized variety within the 1900 O/CC Morgan Dollar series, and some varieties can be more valuable than others.
• Uncirculated Condition: An uncirculated coin signifies it was never used in commerce and remains in mint state with sharp details and full luster. This is highly desirable for collectors and maximizes the value.

Valuation Challenges:

• Grading is Crucial: For an accurate value assessment, the coin's condition needs to be precisely graded by a reputable professional coin grading service like PCGS or NGC. An uncirculated grade can range from MS60 (minor imperfections) to MS70 (perfect mint state). A higher grade translates to a significantly higher value.
• Market Specificity: The specific value of VAM 11 coins can vary depending on market trends, overall coin condition, and collector demand for this particular variety.

Estimation and Recommendations:

While an exact price can't be determined without professional grading, here's a general range based on available information:

• Uncirculated (MS60-MS63): VAM 11 examples in this range can potentially fetch between $4,000 and $10,000.
• Uncirculated (MS64+): For coins graded MS64 or higher, with exceptional eye appeal and minimal imperfections, the value can climb significantly, potentially reaching $20,000 or even higher depending on specific details.

Here's what you can do to get a more precise valuation:

• Professional Grading: Submit your coin to a reputable grading service like PCGS or NGC to determine the exact grade. This will significantly impact the value.
• VAM Verification: Consult a professional numismatist or online resources to confirm the VAM 11 variety attribution.
• Market Research: Search for recently graded and sold VAM 11 1900 O/CC Morgan Dollars in uncirculated condition. Look for coins with similar grades from reputable auction houses or coin dealers.

By following these steps, you'll gain a more accurate understanding of the potential value of your 1900 O/CC Morgan Dollar VAM 11 in uncirculated condition.
