Assortment Of Russian Stamps. ID Help

Hello. A variety of Russia stamps. Any info about the dates and overprints or surcharges? Thanks!

From what I can see, the top two overprinted stamps are postage dues J6 and J9, minimum value (issued under Soviet rule). The other two surcharged stamps are Scott #219 and 222 also very common (some more or less expensive varieties exist). These are imperial Russia stamps surcharged with USSR overprint. Others need to be looked at to identify.

I really appreciate your help, Danko. I will take a few better pics shortly and post.

I'm sorry, I should've been more clearer. By "to be looked at" I meant to physically look at the stamps. They can be on 3 different types of paper, plus one issue with varnish design on the face, not visible on scans. However, if you concern about the value, then those that shows watermark-like vertical or horizontal lines on the back of the stamps, worth few dollars mint; those on wove paper and with varnish, have minimum value. Czar Peter the Great stamp can be 112 or 139 depending on what is on the back of the stamp, both worth about a buck or two.

See if this website will help identify some of your worldwide stamps. I didn't really used, but seems to be worth a try http://www.stampworld.com/en_US/maps/Europe/

Thank you again Danko, for all the usefull information!
