Your Birkin is exactly the investment you think it is.

The famed Hermès bag has appreciated 92 percent on the preowned market over the last decade, according to a new report from secondhand retailer Rebag. That’s more than double the retail price increase recorded at the French masion over the same period, which sits at a cool 43 percent, according to WWD.

In general, Hermès outshone all the other luxury brands on the secondary market this year, with its average value retention sitting at 138 percent, data from Rebag’s 2025 Clair Report showed. The sky-high figure is a 38 percent increase compared to figures from 2024. A high demand for Hermès’s bags and newly introduced shopping restrictions by the fashion house, such as limiting buyers to two quota bags a year, played a large role in the boost.

Throughout 2025, eight offerings from Hermès were sold above their retail prices, according to WWD. The Kelly Mini II, for example, sold for 282 percent over its original sticker price, while the Sellier Birkin was snagged for 183 percent of its original price tag. And with news coming earlier this year that the house will make more handbags to meet rising demand, with four new factories on the horizon, that may have an effect on the resale market yet.

Of course, Hermès wasn’t the only luxury standout of 2025. The Row was also a darling of the year, hitting “unicorn” status for the first time, the annual report says. Bags from the brand had a 97 percent retention rate on the secondary market. Miu Miu, often the hottest brand of the year, also stood out for its retention rate of 104 percent in preowned sales.

In general, nostalgia played a large part in resale trends this year, with the comeback of the Louis Vuitton x Takashi Murakami collection driving interest to previous offerings—sometimes resulting in preowned sales climbing by 143 percent. Moving over to the watches and jewelry category, Rolex stayed fast at a 104 percent retention rate, up 4 percent from 2024. Van Cleef & Arpels, meanwhile, had an 112 percent retention rate, strongly due to demand for its Sweet Alhambra line.

For its study, Rebag turned to its Comprehensive Luxury Appraisal Index for Resale (a.k.a. Clair), which analyzes sales from the past 12 months across all categories and brands to see how values shift during the period. On the whole, 2025 was a rather active year for luxury resale, data shows. Might be time to do some shopping—investing?—then.
