Hello Bianca -- You have a silver dollar designed by a man named George Morgan, so collectors call coins like yours Morgan Dollars. They are highly prized collectibles.
Your 1901O specimen is a 'common date' coin like most of the dates and mint marks in this series. 1921 is the most common of the common dates, as there were hundreds of millions of the 1921 coins made. Coins with better dates, not common dates, are listed below. They are more valuable.
These come in both bronze and nickel silver. The silver ones are worth slightly more. However, both are common and do not command strong collector value.
worn: $1 US dollar approximate catalog value
average circulated: $2
well preserved: $4
fully uncirculated: $8
worn: $4 US dollar approximate catalog value
average circulated: $6
well preserved: $10
That tiger looks like he means business! The British had pulled out of India by 1948. Two years before they did, they minted these rupee denominations in nickel. They are nice looking coins, but not very valuable.
Catalog values for these coins are listed below:
worn: less than $1 US dollar approximate catalog value
average circulated: $1
well preserved: $2
fully uncirculated: $4
Venezuela has been minting bolivare coinage with a seven-sided polygon around Liberator Bolivar's portrait since 1998. The designs on the back of the coin are somewhat different, but they all involve the coat-of-arms of Venezuela. Denominations are 10, 20, 50, 100, and 500 bolivares.
These coins are made of non-precious metal and all dates and denominations are worth small amounts. Typical catalog values for all coins, even the large 100 and 500 bolivare pieces, run like this:
I believe your coin is in the picture ... or at least close to it. Yours is dated 1843. This one is 1854 with a slightly different design.
New Brunswick minted these tokens -- half penny tokens and penny tokens -- in 1843 and 1854. All coins carry essentially the same value, so the discussion below applies.
average circulated: $100
well preserved: $300
fully uncirculated: $1000
The Lion and Sun, or Shir-o-khorshid, is one of the better-known emblems of Iran. Between 1310 and 1332 Iran issued several different denominations of dinar coins made out of bronze and aluminum bronze. Don't be fooled by the date, these are modern coins. It is an SH (solar Hejira) date, which is based on the life of Muhammed. To get the AD (Gregorian) date, add 621 to the SH date. In other words:
AD date = SH date + 621
For a 1317 coin, the AD date is 1938.
I couldn't find a good picture of a 1 penny coin for Bryan, but you get the idea with this 2 pence coin. These small denomination silver coins have been packaged in Maundy Sets and given out during church services on Maundy Thursday (the day before Good Friday, when Jesus Christ ws crucified) for centuries. The sets left intact are in uncirculated condition, or close to it, so that makes them quite valuable. You can divide, very roughly, the 4-coin set value by 4 to get a single coin value.
These are modern coins made of aluminum. Because of that, they do not carry much value. Some of the older dates begin to pick up a little collector value. Also, some coins minted in 1966 and 1967 are made of silver and these are quite valuable (see below)
All these coins have the large numeral 1 flanked by leaves. The reverse is slightly different based on date. Here are some typical catalog values:
