In this fast-paced city of Hong Kong, we at Kam Hoi Shing deal with time every day. Others see seafood as ingredients; we see seafood as the sediment of time and family memories. Today, I want to share a real buyback story that happened last week.
A kraft paper bag carrying the warmth of years
That afternoon, Uncle Li from Sham Shui Po came to our store. Uncle Li is 68 years old this year and is a retired secondary school teacher. Recently, he has been preparing to immigrate to Canada to reunite with his daughter's family in Vancouver. While cleaning out his old residence in Kowloon, he found several items wrapped in layers of old newspapers and kraft paper under the bed in an old camphor wood chest.
"Kam Shing, these were bought by my mother over thirty years ago. Back then she always said that when I one day became weak, or when my wife gave birth, she would cook them to nourish the body. But they've just been left for decades. Now I'm old and don't know how to prepare them, and I'm worried about customs confiscating them if I take them abroad. I heard from friends that you are honest in your work, so I brought them to you for appraisal." Uncle Li said as he carefully unwrapped the paper.
Appraisal: "Aged Broad Stomach Fish Maw" to Preserve Beautiful Time
The moment the paper wrapping was fully opened, my eyes lit up. Before me was a superb aged fish maw (see attached photo).
I put on gloves and held it carefully in the palm of my hand to examine it. From the photos, everyone can clearly see:
-
Color and PatinaThis fish maw shows a charming deep golden yellow color, with a naturally formed old patina on the surface. This is the best evidence of decades of oxidation, something that modern techniques cannot replicate.
-
Thickness and Flesh QualityI specifically viewed it from the side (as shown in Figure 4). Its flesh is extremely thick, with plump edges. It feels heavy in the hand, with a texture like a piece of fine amber.
-
Collagen Patterns and DetailsLooking toward the light, the natural grain on its surface is clearly visible and closely knit. What is most remarkable is that the old hemp rope used during traditional drying is still preserved at the end. This is not only a mark of age but also indicates that it has been kept in a dry condition without dampness or mold.
'Uncle Li, your mother really got top-quality stuff back then,' I said to him with a smile, 'This is a very standard "aged Guangdutong," at least over 30 years old. Just look at the thickness and dryness; it has been preserved very perfectly.'
Upon hearing my words, Uncle Li breathed a sigh of relief, and a trace of nostalgia flashed in his eyes: "Yes, mother always saved the best for us."
Integrity Appraisal, Conveying Value
In the seafood buyback business, many unscrupulous sellers take advantage of customers' lack of knowledge to deliberately find faults and lower the price. But our principle is:To ensure that every precious seafood item receives respect that matches its value.
Based on the appearance, age, thickness, and weight of this large-bellied fish maw, I offered Uncle Li a buyback price far beyond what he expected. Upon hearing this, Uncle Li was very worried and surprised: "Does it really worth that much? I originally thought a few thousand Hong Kong dollars would be enough for tea."
"Uncle Li, good aged fish maw is considered 'precious seafood' in the eyes of knowledgeable people. The price we offer is a respect for this top-grade seafood, and also a respect for your mother's sentiment back then."
After completing the transaction, Uncle Li held my hand satisfactorily and said this money would be just right as a gift for meeting his grandson. Seeing him walk away at ease, I deeply felt the meaning of this work — we are not only buying back seafood, but also finding the next owner who understands and appreciates these treasures that carry family memories.

Fish maw buyback Q&A
Q: Why is Golden Coin croaker maw so expensive?
A: Golden Coin Croaker fish maw is associated with deep waters off South America and in the Indian Ocean. The source describes wild stocks as endangered through overfishing. Thick pieces with distinctive patterns are regarded as top-tier collectibles and traditionally valued foods. The article cites offers above HK$10,000 per tael for large wild pieces, but legality, provenance, condition and current demand must be verified and no price is guaranteed.
Q: How to distinguish real and fake Golden Coin croaker maw?
A: Real Golden Coin croaker maw has distinct features: thick pieces, yellowish-red flesh, coin-like embossed patterns, and a golden sheen when held up to the light. Some market products use other croaker fish maw as counterfeits, requiring expert appraisal. When we visit, we use ultraviolet light, touch, and pattern inspection threefold to verify.
Q: I have a piece of fish maw at home and don't know if it's Golden Coin croaker. What should I do?
A: Send a clear photo to us via WhatsApp for an initial assessment. If it is suspected to be Golden Coin croaker, we will arrange a professional expert to appraise it on-site, with full video recording to ensure fairness.
Q: How long do I have to wait for an on-site appraisal?
A: Within the 18 districts of Hong Kong, Kowloon, and the New Territories, we generally arrange for an expert to visit within 24 hours. Remote areas or outlying islands (such as Cheung Chau, Peng Chau, Lamma Island) may require a 2–3 day appointment.
Q: Can I get an invoice after the transaction is completed?
Answer: Yes, you can. We have an official commercial license, which allows us to issue receipts and transaction certificates, making it convenient for clients to record asset disposals.
Q: How can I get the fastest quote on WhatsApp?
Answer: Send photos of the front, back, and side, and include a $1 dollar coin or ballpoint pen for reference. If you have weight data (weighed by electronic scale), attach it as well, so you can get a preliminary range closer to the transaction price.
