In the second-hand market, the following brands of cowhide bags usually hold their value better:

1. Top luxury brands

Hermès
The best way to maintain value: classic models such as Birkin, Kelly, Constance, especially those made from rare leathers (such as crocodile or ostrich) or in limited edition colors, often have second-hand prices that exceed the official price.
Reasons: brand status, scarcity (need to purchase in combination), top-notch craftsmanship and materials.
Chanel:
Classic models: 2.55, Classic Flap, Boy Chanel, etc., classic design + brand premium, stable second-hand price.
Price increase strategy: The brand has frequently adjusted prices in recent years, pushing up prices in the second-hand market.
Louis Vuitton
Popular models: Speedy, Neverfull, and monogram series (such as the Neverfull medium handbag), which have strong liquidity and high value retention rate.
Reasons: High brand recognition, classic design, durable materials (such as Monogram coated canvas).
2. High-end luxury brands

Gucci
Value-preserving models: Classic designs such as Dionysus and Jackie 1961, especially the presbyopic series, are highly recognized in the second-hand market.
Note: Some seasonal or co-branded items may depreciate due to a decrease in popularity.
Prada
Value-preserving model: Galleria Killer Bag (Saffiano Leather), classic design + durable material, stable second-hand demand.
Risks: Nylon materials or overly avant-garde designs may have a lower value retention rate.
Burberry
Value-preserving models: Classic checkered cowhide bags (such as The Banner), which have strong brand identity, but you need to pay attention to the maintenance of the color.
3. Niche high-end brands

Delvaux:
Used by the Belgian royal family: classic models such as Brillant and Tempête have great premium potential in the second-hand market due to their scarcity and exquisite craftsmanship.
Moynat:
Low-key luxury: Handmade bags such as Rejane and Gabrielle are favored by collectors in the secondary market because of their low production and exquisite craftsmanship.
4. Affordable luxury and designer brands

Coach:
Value-preserving models: Classic presbyopic series (such as Tabby and Willis), especially vintage models, have appreciated in value due to the rise of the retro trend.
Michael Kors:
Basic styles: Some classic cowhide tote bags or crossbody bags have good liquidity in the second-hand market due to their high cost-effectiveness.
Key factors affecting the value retention rate
Classic design: simple, versatile, timeless styles are more valuable.
Materials and craftsmanship: top-grain cowhide, durable stitching, and high-quality hardware improve value retention.
Limited edition and co-branded: Scarcity drives second-hand premium (such as the Supreme x LV co-branded model).
Condition and maintenance: Bags without obvious wear, stains, or hardware scratches are more likely to sell for a higher price.
Complete accessories: The original packaging, dust bag, invoice and other accessories are complete to enhance the value.

If you are looking for a high rate of value retention, you should give priority to classic cowhide bags from Hermès, Chanel, and Louis Vuitton, and pay attention to maintaining the color and preserving the accessories. For those with a limited budget, you can pay attention to basic or second-hand models from brands such as Coach and Michael Kors, but be wary of the risk of depreciation of seasonal popular models.
