You need to know if you have "just a replica" or a replica bullion coin. Most replicas are made of plated base metal so they're only worth a few bucks. If it's an actual bullion coin it's worth whatever the gold it contains sells for at the current market price. If it's a bullion coin it'll probably have the weight and purity stamped on it somewhere. If not, it's probably just a cheap copy. Your can always check with a dealer or appraiser who can perform a purity test, if you want.
A dollar.
$27 to $42,000
About a dollar depending on condition and that isn't a rare year for Indian heads
Assuming it's circulated and no mint mark $20.00 to $40.00 in collectible condition.
You have in your possession a 1897 Coronet Head $5 Half Eagle - if this coin is in fine condition (F12), its value is: $250.
The 1897-S Morgan is a high mintage, common issue. Retail values run from $32.00-$45.00 for circulated coins.
With the date of 1897 the coin is a Barber Half dollar and values for most circulated coins runs from $13.00-$192.00 depending on the grade. With that price range I suggest having it graded by a collector or dealer for a better idea of value.
$500 from 2010 would be worth $11,700 in 1897.
Assuming that you're referring to an American cent and not a British penny, 1897 is not a rare date for Indian Head Cents. In average circulated condition it's worth about a dollar. If the LIBERTY in the headband is complete and easily readable it's worth about $2.00. A nice uncirculated one is worth about $25 - 30
The Dominion of Canada 2 Dollar note was issued with three different signatories and is worth between $10,000 and $30,000 in uncirculated condition. A Very Good condition would be worth $350 to $5,000 depending on specific issue.
