Well that's the real joy at the end of the day isn't it? Some of my favorite stamps are worth pennies. Some of my least favorites are worth thousands.
If you're just getting started, one thing I highly recommend then is looking at the Scott catalog site. You can get online reference catalogs, and only need to buy the countries you need.https://www.scottonline.com/
it will help you find the stamps you're looking for, and what their value is.
Look forward to seeing more of your stamps and helping you with identifying them.
