No. Not even remotely authentic. That being said, that's a nice Lucite (paperweight?) of some vintage (maybe 40-50 years old), so since they are older replica coins inside a vintage souvenir item, they might have some modest value anyway. $5-10 on the low end and $20-25 on the high end, I'd estimate. @H8_modern collects such things, and is likely not the only person who does.
