Off-metal 1974 Roosevelt dime struck on an aluminum Philippine 1 Sentimo planchet. The coin weighs 0.5 grams and so is extremely lightweight. There aren't many Roosevelt dime off-metals since most coin's planchets are larger than a dime's, and this is a very rare off-metal, being the only one for the date we're aware of. Also, one of the few aluminum off-metals out there.
