That's a fair question and I'm not sure I can answer it. My opinion is it has little to do with the price. I know of no specific collectability of
Russian
Captures. People tend to classify these in three categories. All matching original which is the cream of the crop with even shot out bores bringing high dollars. Next is the non-matching bring back, usually most parts except the bolt match. Then there are the mismatched put together's which include rebuilt sporters, Russian Captures and
Yugo
and other captures. Prices on all these vary on the individual, what they want and what they are willing to pay. This last group generally is the lowest priced although prices for this group have gotten a bit ridiculous also. My personal preference for myself would go down the list from top to bottom. the reality is I have a Russian capture that I removed the purple shellac from and restored the front sight guard and locking screws because that's what I could afford at the time and I'm not planning to upgrade in the near future. I want my rifles to have the appearance they would have had during WWII. Some will say I did harm in removing the shellac but that's their opinion and I'm not planning to sell it so it is what it is.
If your son wants an RC, I'd pass on this one even it if was priced lower. If he just wants a K98, I wouldn't have a problem buying it if it were priced lower. I'm just thankful that I started collecting when I did because I would have trouble justifying the prices on a lot of these now. I have mine on here, it was 10 years ago I bought it and I paid $200.00 for it. Photos of it when it was partially finished are here:
