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.
The coin is not solid gold. The composition is .900 gold and .100 copper. The 1897 Double Eagle was struck at the Philadelphia and San Francisco Mints but both are common and easily acquired in all grades and values are the same. Circulated examples have retail values of $1,340.00 to $1,540.00, only a $200.00 spread over 9 different grades. Mint state examples are $20.00 more at $1,560.00.
Those are novelty copies. Worth zip.
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.
The 1897-S Morgan is a high mintage, common issue. Retail values run from $32.00-$45.00 for circulated coins.
You have in your possession a 1897 Coronet Head $5 Half Eagle - if this coin is in fine condition (F12), its value is: $250.
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.
1897 is a common date for Morgan Silver Dollars, circulated coins are valued at $17.00-$26.00
The 1897-S MORGAN dollar is not scarce or rare, an average retail value for the coin is $26.00-$32.00.
