A PCGS slabbed coin is one that was submitted to a professional grading service and placed in a coin safe holder. You pay a fee to have the coin graded and using the 1-70 system they send you back what they believe the coin's grade is and from there you can determine what the market value should bring. Here's their site http://www.pcgs.com/.
This is my first PCGS slabbed coin.
Here's the stats for this coin....
Type/Country: 4 Paisa / Nepal
Year: 1955
Mintage: Unknown.
Metal: Brass
Value: XF-45 $3.00+ because it is verified. Maybe only a few cents more.
A slight update on my collection so far. I've recently bought some silver dimes on eBay, nothing special, and found some foreign coins in my change but older U.S. coins have been few that I've got from pocket change. Mostly the 1944 and 1946 wheat cents, which as you know are barely worth twice face value. Hopefully I'll have money to spend over the holidays and get some nice coins from all the holiday shopping.
