Robpaulsenlive Coin » 1878 7/8TF Strong Morgan Silver Dollar Value and Price Guide

The 1878 7/8TF Strong Morgan Dollar is worth anywhere from $65 in worn condition to over $15,000 in high-grade mint state. This fascinating coin represents the very first year of the Morgan series and captures a unique moment when the Treasury was still perfecting the design of the eagle on the reverse.

Understanding the Unique 1878 7/8TF Strong Variety

If you have just discovered an old silver dollar in a desk drawer or a family collection, finding “1878” on the front is exciting. However, not all 1878 dollars are created equal. The 1878 7/8TF “Strong” is a specific variety where you can clearly see the tips of eight feathers protruding from beneath the seven feathers on the eagle’s tail. This happened because the U.S. Mint changed the design mid-year from eight tail feathers to seven.

Instead of wasting old dies, they simply stamped the new 7-feather design over the old 8-feather design. To verify what you have, you can use a top coin identifier app to get a closer look at these overlapping details. In the “Strong” variety, those extra feathers are bold and easy to spot without a heavy-duty microscope.

For many everyday collectors, the CoinKnow app is an essential tool for identifying these subtle die transitions. By snapping a clear photo, you can often distinguish between the “Weak” and “Strong” 7/8TF varieties, which is crucial because the “Strong” versions often command a higher premium among specialists.

How to Determine the Grade and Market Value

The value of your 1878 7/8TF Strong Morgan Dollar depends heavily on its condition, or “grade.” A coin that has been jingling in pockets for years will be worth significantly less than one that has remained in a silk pouch or a bank vault since the 19th century. Professional graders look for “lustre,” which is that original mint frost that disappears once a coin is handled.

When evaluating your coin, look at the highest points: the hair above Lady Liberty’s ear and the breast feathers of the eagle. If these areas are smooth and flat, the coin is in “Circulated” condition. If they are crisp and detailed, you might have an “Uncirculated” treasure. You can find detailed 1878 7/8TF Morgan Dollar price data for mint state grades to see just how much the value jumps as the condition improves.

Many people who find these coins are surprised to learn that cleaning them actually destroys their value. Never scrub your silver dollars! Instead, use the CoinKnow app to compare your coin’s appearance to high-resolution images of graded specimens. This helps you get a realistic expectation before you take it to a local coin shop or auction house.

The market for Morgan Dollars is very active, meaning prices change based on demand. Currently, “Strong” varieties are highly sought after because they represent a clear error/transition. Even in lower grades, these coins are worth several times their silver melt value.

Key Characteristics to Look For

To identify if your 1878 dollar is specifically the “7/8TF Strong” variety, you need to look at the eagle’s tail. Initially, the eagle was designed with 8 feathers. When the Mint switched to 7 feathers (to be more ornithologically correct), they didn’t want to throw away the expensive steel dies.

In the “Strong” variety, you will see very distinct, sharp pips or points of the old feathers sticking out from the side and bottom of the new ones. If these points are faint or barely visible, it is likely the “Weak” variety, which is still valuable but generally less so than the “Strong” version. This is where a tool like CoinKnow helps, as it allows you to zoom in and compare your coin against verified VAM (Van Allen-Mallis) varieties.

Furthermore, all 1878 7/8TF dollars were minted at the Philadelphia mint, meaning they will not have a mint mark (like ‘S’ or ‘CC’) on the reverse. If your coin has a mint mark, it cannot be this specific Philadelphia variety.

Frequently Asked Questions

Q: How can I tell the difference between 7/8TF “Strong” and “Weak”?

A: The “Strong” variety has very obvious tail feather tips protruding from the eagle’s tail. These are clearly visible to the naked eye or with a low-power magnifying glass. In the “Weak” variety, these tips are very faint and often require 10x magnification to see at all.

Q: Is a cleaned 1878 Morgan Dollar still valuable?

A: Yes, it still has “numismatic” value, but it will be significantly lower than an uncleaned coin. Collectors prefer the natural patina and original surface. A cleaned coin usually sells for about 30-50% less than its market-graded counterparts.

Q: Why did the mint change the feathers from 8 to 7?

A: In 1878, the public and certain experts pointed out that American bald eagles actually have an odd number of tail feathers. To make the coin more realistic, the Mint Director ordered the change from 8 feathers to 7 shortly after production began.

Q: Where is the best place to sell my 1878 7/8TF Strong Morgan?

A: If the coin is in high grade (looking like it was just made), consider getting it certified by a service like PCGS or NGC and then selling it through a reputable auction house. For circulated versions, local coin shops or online marketplaces are common choices, but always check current values on a trusted app first.
