10xloupe- I am one who really likes this type of coin, but beware since there are so many counterfeits of the late 19th century 5 peseta coin. I go to a few coin shows whenever I am in Barcelona and there are tons of these for sale. The only problem is that attending this show is like being in a boat and looking for the island of authentic coins as you sail through a sea of fakes. Seriously, about 4/5 of these coins I saw in Spain were fakes. In fact, at some shows I saw hundreds for sale from many dealers, and most were fakes.
A true, sad story: I met the father of a family friend who lives in Spain. His father proudly showed me his collection of coins. I did not have the heart to tell him that of his about 100 or so coins, about 75 or so were modern, bad fakes.
