On
2008, a 5€ coin (mintage : 2 millions) was sold in post offices (silver 50%) with success and this coin was circulating for a while.

At least I have seen some of them in circulation. But when people learnt that these coins are valid only in France, they were reluctant to get them for change in stores and these coins gradually disappeared from circulation.
The year after a
10€ of the same series "sower running" was issued with the same high mintage (Silver 90%) and were collected by many people but barely found in circulation.

These two coins 5€ and 10€ got high success. It was a little bit remaining the old good times of the sixties with the 5 Francs and 10 Francs silver coin.

[edit: 15€, 25€ and 50€ from the same series "sower running" with a low mintage, never circulated]
Then on 2010 the
first 10€ region series (Silver 90%) was also sold in post offices of the related regions, with very high success

and you had to call friends in each region to get these coins. It was a little bit difficult for overseas departments ... Very few of these 10€ coins were found in circulation and post offices were quickly out of stock.
Some of these coins are worth six times more expensive today like for example "
Champagne - Ardennes"
On 2011, the
second series had very nice design and despite a lower silver grade (Silver 50%) these coins were appreciated and thoroughly collected.

On 2012 the
third and last region series (Silver 50%) dedicated to well-known characters did not raised much excitement.
Then on 2013 a very nice series of 5€ (
Liberté, Egalité, Fraternité)

(large mintage of 2 millions each coin) was a success despite a new lowering of Silver grade (33%).

[edit: these coins were quickly captured by collectors and so never circulated]
Since then 10€ series 2014, 2015, 2016 with the 33% silver grade

no longer interest anyone.
[edit: all these coins have legal tender in France]
