Has the price doubled for numismatic coins the last 10 years?

For about 10 years ago you could buy the low-graded Byzantine gold coins for about 200-300 Euro. All the above were sold for 200-300 Euro in auctions.

Byzantine Solidus or Hyperpyron normally weight 4,5 grams with 98% pure gold. (For Hyperpyron maybe 90% as they addded silver?)

But today those coins above would be sold for about 500-600 Euro.

The price has raised because the gold price has pushed them up.

I want to ask:

Has the price for numismatic coins doubled in the last 10 years?

How about Athenian Tetradrachm? Roman Denarius? Or other coins? – Has the price also doubled the last 10 years?

Have prices of ancient coins doubled in the last 10 years?

There isn't a simple generic 'yes' or 'no'. A decent answer would need to be very nuanced. It would vary depending on many factors such as quality, rarity, seller and selling venue, the type's supply-and-demand, etc.

However, as a down-and-dirty small sampling, I just quickly selected 7 ancient coins (4 silver and 3 bronze) of various kingdoms, ranging in cost from $77 to $1100, which I purchased in 2015. Then I checked ACS and VCoins to see sales/list prices in 2025 for the same types in closely comparable quality. I'll spare everybody the math, but the comparative result was an increase of 14%. (That's not a great return on investment, as it averages a mere 1.4% annual gain. But then, I and most all collectors I know well, aren't in this hobby for a portfolio increase.)

Then I did the same with 2 gold byzantine coins I purchased (one in 2014 and one in 2016). The same types in very comparable condition sold/listed in 2025 for 26% higher. A little better in terms of investment, with an approximate 2.6% annual increase. Of course... both are well below inflation:

I would add the spot price of gold has well more than doubled in the last 10 years.

 

It depends on the coin, the condition and the grade.
