4 marbles found in the surf. Please help with age/desirability. Also, any use restorative polishing or tumbling? They have been in the river for a while!
First is a Vitro conqueror, second needs more pics, third is an Akro patch, and last is a Master. Polishing marbles is usually frowned upon and ruins their value, but is also costly and in few cases it's a way to bring some value back to a marble, but the marble needs to have good value, these are $5 marbles or less in good condition. They are from the 30s-50s
