That sure is an unusual shape, Wes! Not many countries have struck coins in a decagonal shape. This one is a 2 Piso coin from Philippines, dated 1984. Though eye-catching, tens of millions were struck, and catalog values remain low. For common years, 1983 to 1986 and 1988 to 1990, nice looking specimens can sometimes be sold to interested collectors for one or two US dollars.
There are 2 years, 1987 and 1988, that are somewhat rare. For these coins the catalog value goes like this.
2 PISO DATED 1987 OR 1988
worn: less than $1 US dollar approximate catalog value
average circulated: $2
well preserved: $5
fully uncirculated: $10
