It may be a Mint error only in that the coin is an uneven thickness, in which case it would be a planchet error. If the coin is not damaged otherwise (excluding the bubble), though, then it's probably not a provable Mint error. The bubble is probably a lamination problem, which can also be a planchet error. This occurs when the cupro-nickel layer (the "silver" colored layer) separates from the copper middle.

hard to tell. could be the minnasota extra tree error but probably the 3031 quarter
Value depends on what kind of error. please be more specific
The 'Eagle Reverse" was last used in 1998 for the Washington quarters. Look at the reeding on the edge of the coin. You should see a seam an the reeds won't mach up. This is NOT a U.S. mint error coin. It has been altered and has no numismatic collectible value.
State quarter lamination errors retail for about $10.
