Collecting Coins

My husband has tons of worldwide coins and he did not collect them, he have them since he travel anywhere in the world before. I looked them up, I cannot even say what country are those coins from since others hard to read or they are not written in English. There are some are worth if I'll sell them but we will keep them as collections and I will start collecting rare coins soon. I have Sacagawea 2001 $1 coin. I checked in eBay and found out it is kind of rare, so, I am keeping it and will be added to my collection and eventually I could sell in eBay.

About little detail of the woman in the coin-Sacagawea (c. 1787 – December 20, 1812) was a Shoshone woman who accompanied the Corps of Discovery with Meriwether Lewis and William Clark in their exploration of the Western United States, traveling thousands of miles from North Dakota to the Pacific Ocean between 1804 and 1806. She was nicknamed Janey by some members of the expedition.
