You probably own or have seen prized things that once sparked bidding wars but now barely sell. This article shows which five familiar antiques lost their market value and why that matters to your attic, estate sale finds, or impulse buys.
Keep reading to learn how changing tastes, mass production, and collector fatigue turned once-hot items into common clutter so you can spot what’s worth keeping and what to let go.
Franklin Mint collectibles
You probably remember Franklin Mint plates, figurines, and coins marketed as investments. They were mass-produced, so many pieces flooded the market and values fell.
If you kept items in boxes hoping for a profit, most now sell for little beyond sentimental worth. A few signed or rare pieces still fetch decent prices, but those are the exception.
Old Pez dispensers
You might remember Pez dispensers as nostalgic treasures from childhood.
Many common models from the 1980s–2000s have low market value today unless they’re rare, boxed, or in mint condition.
Check for unique heads, licensing errors, or original sealed packaging to find anything worth more.
If you find one at a garage sale, compare it to guides like the PEZ Dispenser Price Guide before assuming it’s valuable.
Beanie Babies
You probably remember the frenzy in the 1990s when Beanie Babies seemed like a guaranteed investment. Most of those mass-produced plush toys never held value and now sell for little more than nostalgia.
A few rare, well-documented pieces still attract collectors and can fetch high prices online. Check current listings and guides before assuming any specific Beanie Baby is worth money, since condition and tag details matter.
Costume jewelry without designer marks
If your vintage brooch or necklace has no maker’s mark, don’t expect big auction prices.
Unmarked pieces were often mass-produced and use inexpensive materials, which keeps resale value low.
You can still enjoy wearing or repurposing them, or sell small lots to collectors who like a particular style.
For help identifying any hidden value, compare similar pieces online and check guides like this vintage costume jewelry value guide.
Collector plates
You probably remember these as holiday gifts or magazine mailers that promised investment potential.
Most plates today sell for only a few dollars unless they’re signed, from a limited run, or tied to a notable artist.
Check condition and backstamps before you list anything; small details often decide value.
For examples of which plates still fetch good money and why, see a guide to valuable collector plates.
