It depends on its mint mark and exact condition. See http://www.numismedia.com/fmv/prices/stdqtr/pricesgd.shtml for an example of the price range.
Assuming the coin is circulated and has no mintmark, the 1888 Morgan dollar is a very common date of the series. Most coins show heavy wear. For an accurate assessment of value the coin needs to be seen and graded. In general retail values for circulated coins are $32.00-$44.00. Values are a market average and only for coins in collectible condition, coins that are bent, corroded, scratched, used as jewelery or have been cleaned have far less value if any to a collector or dealer.
Assuming you have a general circulation issue, that design was issued from 1960 to 2002 when the euro came into use. Many were hoarded post-euro so there's no significant numismatic value.
The exchange rate fluctuated but was around 7 or 8 francs to the U.S. dollar, so your coin's value would be 12 to 14 cents. I'd simply hang onto it as a conversation piece and an example of an old and famous currency that's no longer in use.
51.550.000 coins were struck in 1968.

The "dollar" denomination is of course artificial since these coins are sold as bullion pieces for their precious-metal value. The current price of silver is about $14 an ounce, so your coin is worth approximately that amount.
I don't know. Why does the sun rise?
Why does my heart keep beating?
All these questions were in an old love song.
The real question is how did I accidentally end up on the above persons account?
Maybe you can fix this for this dude who answers questions above.
