Some more things to add about tri-logos. 
Not every figure was released on a tri-logo card.  The four Cantina creatures as well as one or two others (Death Squad Commander I think) were never found on tri-logos.
The two rarest tri-logo figures are General Madine and Jawa.  No other figure comes close to their rarity.  Emperor's Royal Guard is somewhat hard to find, but nothing compared to Madine and Jawa. 

Also, tri-logos were released in the U.S.  I had many as a kid. 

A few years ago, Tom Derby put together a complete set of C9+ tri-logos.
I believe he was asking $30,000. 

Good luck,
Andy

Chris, here's a good thread about those ROTJ 48 backs.
Shawn Gouty completed his run a year ago.  According to him, the hardest to find are:
1) Ben
2) Luke Xwing
3) Han Solo
4) Stormtrooper
5) Chewy.

Hope that helps,
Andy

I can confirm that the sunlight method works extremely well. 
I have used it on carded figures as well as baggie figures. 

Andy

Weequay in baggie sells for $15-$25. 
Can be found tape sealed or heat sealed.

Andy

Congrats on completing your loose collection. 
If you're going after carded figures next, I suggest you find a focus.  Maybe a character or even a cardback/offer focus ... something specific.  You'll get lost if you have a general "carded" focus.  Very lost.

Good luck!

I know it's fake, but it's still sofa king funny.

The guy that tried to get me into Quickscam told me stories of riches and wealth.
He told me he had been doing it for 5 years and that he was just about ready to quit his day job.

Then he got into his 1990 Cadillac and drove home to his trailer park.

There is no right or wrong way to collect.  
But there is a right and wrong way to display.  Even small collections can look nice if displayed properly.  

My main problem with the RS feature is there's not enough vintage representing.
