Aruba 2 1/2 Cent

The Aruba 2 1/2 cent coin stands out for its fractional denomination, a rare survivor from the Dutch guilder era that persisted into the modern florin system.

Struck from copper-plated steel, it measures about 18 millimeters across and weighs roughly 2 grams. The obverse typically bears the effigy of Queen Beatrix, reflecting Aruba's ties to the Netherlands during its minting years. On the reverse, you'll find the denomination encircled by the Aruban coat of arms, complete with a lion and stars.

Production ran from 1986 through 2010, though exact mintage figures for individual years are murky—likely scattered in some archive. That said, it's a straightforward piece, free of the embellished tales that collectors sometimes spin.

Not the flashiest coin in the drawer, but it got the job done for small change.
