A medal struck, not as a possible coin design ( pattern), but simply as a piece of art/sculpture in a numismatic form. Many fantasy coins have become collectors items eg. the numerous issues struck following the abdication of Edward VIII and various private designs struck around the time of decimalisation.
Usually a representation of a rare or never issued coin. A good example are the recent fantasy coins of Edward VIII, created in limited numbers, of good quality and designed to fill collectors album holes as the very few contemporary Edward VIII are out of the reach of 99.9% of collectors due to price.
"Fantasy" is a song co-written and co-produced by American singer Mariah Carey and Dave Hall, and recorded for Carey's sixth album Daydream (1995). It is built around a sample of the Tom Tom Club's single "Genius of Love" (1982), which was written by Tina Weymouth, Chris Frantz, Steven Stanley and Adrian Belew. It was released as the album's first single in 1995 (see 1995 in music), and is one of Carey's most popular songs.
