Could you have more than you imagine your old piggy bank? Ever since the euro currency was rolled out in 2001 old Irish coins have increased in value – and the rarer the better – but according to World Coin Hub even the more mundane Irish coins could now earn you a pretty penny.

You never know how much the coins could be worth and the best thing to do is to bring them to your local coin dealer. Alternatively, have a look on eBay where coins are regularly sold. According to World Coin Hub, the price you get has to do with the condition of the coin. On their site they list the best case and the worst case scenario for prices.

- 1943 two shilling: $5,500 to $33,300 (€5,000 to €30,000)

- 1937 1 shilling coin: $27.70 to $2,200 (€25 to €2,000)

- 1934 two shilling: $55.50 to $2,442 (€50 to €2,200)

- 1937 half-crown: $111 to $ 4,441 (€100 to €4,000)

- 1943 half-crown: $220 to $ 4,995 (€200 to €4,500)

- 1985 half-penny: $5.50 to $550 (€5 to €500)

- 1986 10 pence: $166 (€150)

- 1985 20 pence: $1,443 to $8,879 (€1,300 to €8,000)

Back in 2012 experts said that coins from as recently as the 1980s and 1990s were worth thousands of euros. For example, at the time a 1985 copper-colored 20p piece (the one that depicts a horse) could be worth at least $11,096 (€10,000) in an auction. Similarly, the 1992 10p coin could bring in between $5,500 (€5,000) and $11,096 (€10,000). Both of these coins were only produced in very small quantities, making them rare today.

Mike Kelly, one of Ireland's foremost coin collectors and numismatic experts, said, "It's their very scarcity that makes them so collectible …The fact that anomalies like those coins exist gets collectors really excited.”

He added, “Sometimes it's the coins you don't think much of that can be the very desirable ones.”

You heard the experts! Get upstairs and root out the old coins you have floating around. You never know how much they could be worth.
