I have a 1998 5ptas. I am wondering if these coins have any collectable value? Sorry I don't have a scanner or camera. I got this coin from a little gas station here in the county. It is located exactly between two towns and is aptly named Midway.
Are you certain of the date ? The 2005 Krause does not list one as being struck in '98. They do list several others in the late '90s though. Assuming it is one of those dates - to those who collect Spanish coinage - yes it has collectible value. But only because they like the coins. As for monetary value - even in Unc it is worth less than $1.
This dime sized 5 pesetas coin is aluminum bronze and #833 in Krause's Standard Catalog of World Coins. It's worth about .25 at best. Spain now uses the Euro system.
