***Hi braintrust! I was hoping you can help me here, so about a decade ago I started collecting soviet stamps then stopped due to getting busy at work. I recently started looking into that collection again and realised that it was incredibly weak till about 1958, almost all medium rarity to rare stamps are missing which means it'll be a somewhat painful exercise (i collect mint only but I don't mind hinged or even without gum if it means it can save me some money!)
My question is, what would be the smart financial approach here? should I look for near complete collections until the late 50's? And if so where do I find those? I had a look on ebay and stamp auction network, the former has a couple of astronomically expensive sets and the latter has collections with very very concise descriptions and sometimes no photos whatsover.
Or should I go down the Delcampe / Hipstamps etc road and buy missing stamps one by one?
I tried to share scans of my Russian album stored on Google photos to give you an idea on what im missing but unfortunately this wasn't allowed ..
