Sound Test\u003c\/h4\u003e \u003cp\u003eGenuine silver coins, due to their high silver content and strong strike pressure, will emit a soft, prolonged, and pleasant ringing sound with a lingering echo when lightly tapped or blown on. If the sound is sharp and short (like metal sheet) or dull and muffled (like lead-tin alloy), it is highly likely to be a low-quality counterfeit.\u003c\/p\u003e \u003ch4\u003e2. Patina Inspection\u003c\/h4\u003e \u003cp\u003eOld silver dollars, after a hundred years, will form a natural layer of oxidation on the surface called \"patina.\" The patina on genuine coins transitions naturally in color, varying in depth and layering, and is not easily removed. Artificial counterfeit patina usually has a dull color (like uniform black or light yellow), floats on the surface, and may even have a pungent chemical smell.\u003c\/p\u003e \u003ch4\u003e3.

Carefully observe whether Sun Yat-sen's hair strands are distinct, whether the double flag pattern on the reverse is clear, and whether the strokes of the English letters are clean and crisp. Genuine coins have deep lettering and a flat field; counterfeit coins often have blurry lettering, feathered edges, or sand holes.\u003c\/p\u003e \u003chr\u003e \u003ch3\u003eKey Factors Affecting the buyback price of Old Silver Coins\u003c\/h3\u003e \u003cp\u003eMany customers ask, \"How much is my silver coin worth?\" In fact, the price of silver dollar buyback is not fixed and mainly depends on the following core factors:\u003c\/p\u003e \u003cul\u003e \u003cli\u003e \u003cp\u003e\u003cb\u003eCondition:\u003c\/b\u003e This is the most important factor.
