I also have this Ronald McDonald uncut bowling ball (no holes) - any significant value to it? Anyone has seen those?

There is one on Ebay at the moment for about $175 but others on the net have sold for as little as $10 so I guess it all depends on what people will pay for it.

I have seen the one on ebay, but asking price can be anything... Those sold for $10 I believe are much smaller versions of the big one. I think. But I could be wrong.

I am a bowler and my son owns a pro bowling shop. Many bowler manufactures to appeal to junior bowler's such as dora the explora and tweety bird, turtle ninja's, mickey mouse etc. They sell for $40.00 to 50.00 then $40.00 to have holes drilled. They are also used by adult bowlers for picking up spares such as the 10 or 7 pin cause they do not hook. Many of these balls exist on the market. I suppose someone who collect's McDonalds item's might want one but right now the value is $40.00

all bowling balls are the same size but different weights. If you see smaller ones then they are not a bowling ball, it could be just the way the picture was taken

yeah most of the bowler articles to address to inferior bowler's such as dora the explora and tweety bird, turtle ninja's, mickey abrasion etc.
