Professional Silver Dollar Appraisal: How to Initially Authenticate Old Silver Dollars?

Many collectors, when searching for "Hong Kong high-price ancient coin buying" or "high-price old silver dollar recycling" services, are most concerned about the authenticity and actual value of their collections. For valuable historical coins such as the Sun Yat-sen silver dollar from the 18th year of the Republic of China, Hong Kang Commercial Bank's experienced appraisal team has compiled the following basic "old silver dollar authentication" techniques for you.

Appraisal Dimension Characteristics of Authentic Old Silver Dollars Characteristics of Common Counterfeits / Forgeries
Weight and Size Standard weight is typically between 26.6g and 26.8g, with strict dimensions conforming to the minting standards of the time. Weight is too light or too heavy (often plated with silver over copper, lead, or alloy), with noticeable discrepancies in thickness and diameter compared to the standard.
Sound Identification When tapped lightly on the edge, the sound is clear, prolonged, and mellow, with a unique "ringing tone" characteristic of silver coins. The sound is dull and short (high lead content), or too sharp and piercing (high copper or steel content).
Patina and Surface After years of oxidation, a natural, multi-layered, and strongly adhering "patina" forms on the surface, with a subdued luster (often referred to as a "moist" feel). The patina floats on the surface, with an unnatural, harsh color (often chemically aged or fire-treated), lacking the sense of age.
Edge Milling and Lettering Edge milling is pressed by large machinery, with consistent depth, neatness, and strong definition; lettering and portrait engraving are three-dimensional and clear, with vivid hair details. Edge milling is rough, with inconsistent depth; the portrait face is stiff, and the lettering edges are blurred or have small sand holes left by sand casting.

Analysis of Common Varieties of the One Yuan Silver Dollar from the 18th Year of the Republic of China (Sun Yat-sen Portrait)

The One Yuan silver dollar from the 18th year of the Republic of China (1929) holds immense historical significance in modern Chinese numismatics. At that time, to unify the currency system, the Nationalist government commissioned mints from several countries to engrave dies, resulting in various trial patterns. Different "18th Year of the Republic of China One Yuan varieties" directly influence their secondary market value and "18th Year of the Republic of China Sun Yat-sen silver dollar recycling price."

Pattern Variety Description of Surface Characteristics Collection and Market Rarity
British Mint (Birch) Version The portrait engraving is extremely delicate, with smooth suit lines, and the sailboat on the reverse rides the waves with vivid ocean details and exceptionally neat edge milling. Extremely high (a rare trial pattern, rarely seen in the market)
Italian Mint (Rome) Version The relief of Mr. Sun Yat-sen's portrait is higher, with facial features exhibiting a unique European engraving style, bold lettering, and strong three-dimensional effect on the reverse design. Extremely high (highly sought after by high-end coin collectors)
Japanese Mint (Osaka) Version The engraving style leans towards Eastern aesthetics, with a slightly different expression in the portrait, and the handling of the sailboat and wave patterns on the reverse is delicate and unique. Extremely high (combining historical research and collection value)
Austrian Mint (Vienna) Version The overall design layout is balanced, with subtle differences in lettering compared to other versions, deep edge pressing, and excellent minting craftsmanship. Extremely high (a popular category in international auctions)

(Note: Most 18th Year of the Republic of China silver dollars are trial patterns. If you possess such a collection, we recommend having our coin appraisers provide a free physical assessment.)

Yes. We offer free door-to-door collection across Hong Kong. The more items, the better. We recommend sorting them by type and year in advance to facilitate quick appraisal by our specialists.

Silver dollars | Coins | Commemorative notes. Professional recycling of Republic of China year 18. Will you still accept a one-yuan coin with wear and scratches?

Yes, we will. The appraisal of silver dollars mainly refers to their condition grading (from uncirculated UNC to common circulating G). Minor wear is considered normal circulation marks, and the appraisal will be adjusted according to the grading, but we will not reject them.

How do you appraise special editions (e.g., autographed, Gansu editions)?

Based on rarity and market popularity. Famous varieties such as autographed editions, Gansu overprints, and O-variant triangle-circle coins have extremely high premiums. We recommend sending clear photos of both sides and key features.

Yes. Professional third-party grading (PCGS, NGC, Gongbo) significantly increases liquidity and confidence, and high-grade coins can double in price. We also accept ungraded coins and will provide a professional assessment on-site.
